Electronic Waste and Recycling

When we went to Oskar Winski and were educated on their fairly new Electronic Waste and Recycling program I was intrigued. Electronics are made from hazardous wastes and materials that never go away, on the bright side though electronics are not going away. This being said, electronic recycling is a big business opportunity and environmental initiative. My thought is why not just reuse materials from old electronics to make new electronics.

"This is money."



Attached below are a few companies and initiatives in other states and around the country that focus on Electronic waste and recycling.

Must See Documentary: TRASHED



Trashed an environmental documentary produced by Jeremy Irons portrays the everlasting problem of global waste. Executive producer and actor Jeremy Irons digs deep into the societies and populations most affected by the issue. He comes to find out and simply portray the lives of third world country citizens and the lives of beautiful animals. The people affected by global waste first hand are those in third world countries. They are mostly poor and native to the lands where countries such as the United States dumps their every day trash. What people do not understand is that not only does it affect them but us as well. And not only us but every living organism in the world. When we bury plastics and materials that are not compostable then we harm the environment. This documentary explores all of these different ideas. Scholars and well known people around the world on the subject of global waste comment on the idea.



Above is the trailer. Enjoy.

The Most Eco-Friendly Home in America


I've always been interested in how to save money and help the environment through changes in your home.  We spend alot of money on energy and other things to keep our home going, and this creates alot of waste and negative environmental impact.  I think there is a large amount of potential for Americans to save money and reduce their environmental impact if they make minor changes to their home.  This video shows a family that built an extremely efficient home that is sustainable.  I'm skeptical that the innovations didn't affect the price, but either way, the home is very cool and shows how we can improve the sustainability of our homes.

Expanding Waste Management




After visiting Covanta this past week, I became interested in their progression in the field of waste management. I was very impressed with their facilities structure and order throughout each area and was curious as to if they were looking to expand--and if so where.



I found an article that details their reasoning behind the new partnership in which they have created with the corporation Clean Energy Fuels. These two companies are looking towards the opening of yet another facility like Covanta, to "compliment" the original. This new building will be built with minimal impacts on the surrounding environment. But their mission doesn't stop there, both companies are still searching for additional locations, throughout the United States to continue on in their quest for nationwide waste management.



I believe that the addition of another "Covanta like" facility would be greatly beneficial to any community. I hope to look into this expansion in the near future to see some form of progression because I now see the benefits that a company like Covanta can provide. 

Recycling: Not just paper, bottles and cans

The article I read was about the importance of water recycling.  You may have heard about the need to conserve water and be careful with how we're using it, but recycling it is probably a new idea. Most people think recycling is simply for different types of metals, glass, plastic, and paper, however water is now being added to that list.  One way water is being recycled is through "gray water." Gray water is reusable wastewater from residential, commercial and industrial bathroom sinks, bath tub shower drains, and clothes washing equipment drains.  Gray water is reused onsite, typically for landscape irrigation. Also, water recycling refers to the technological ways of speeding up nature's natural recycling process.  So what are the benefits of recycling water? Well, there are many.  First, it is extremely useful for irrigation, in places like golf courses, public parks, and other landscapes.  It can also cool water for power plants and oil refineries.  Recycling water also has many environmental benefits, such as decreasing pollution and increasing demand for an additional source of water, which would help diverge demand from precious and sensitive ecosystems.  As you can see, water recycling is becoming an influential part of our transition into a healthier world, and has many benefits.

Biofuels: The Future of Waste Management


A new method of waste management is on the horizon and its name is biofuel. The has been a recent breakthrough in biofuel technology that allows agricultural waste to be converted in to alternative fuels. Over the past few years biofuel production has been limited to only a handful of small pilot production plants. However recently two companies have come together to create the first large scale biofuel production plant on the planet. The process will consist of collecting wood garbage from farms and paper waste from papers as well as residential households. The fuels created will create only a mere one-sixth of the carbon dioxide to an equivalent amount of petroleum.

Biofuels are created by taking biomass such as algae, plants, wood, or agricultural waste and stripping all of the available oxygen from it. The remaining element are hydrogen and carbon and together they create compounds called hydrocarbons. These hydrocarbons contain stored chemical energy from photochemical reactions during photosynthesis while the biomass was alive. The biofuel that is created from this process is called Celluosic ethanol. This process created renewable energy while not diverting food away from animals and humans

We Can Use Plastic As A Raw Material

          After doing a little research of my own, I stumbled upon a video from TEDTalks of an idea given by Mike Biddle. In the video he give states that less that 10% of plastic trash is recycled in comparison to the 90% of metals. The reason behind this is because the two different raw materials have different and complicated ways of sorting the material. Metals are little bit easier because of the variation in density and magnitude, though plastics when all said and done, come from oil and the similar materials.

          I am interested in the topic of recycling plastics because they do not go away like we think they might. Most plastics end up in landfills or polluting the atmosphere because of the toxic gases released while burning them. It is also known that plastics end up in third world country landfills. Mike Biddle addresses this issue as its own. In my opinion no first world country such as the United States should be damaging a third world country such as parts of Mexico and central America. Though I do not have pictures, I witnessed this issue first hand in Tijuana, Mexico on a mission trip. We found my 5yr old brother at the time playing with the other kids on the side of a mountain. Which come to find out was mound of trash built up over the years.

          In the video, Mike Biddle shows his audience how he himself along with other acquaintances have developed a cheap and incredibly efficient plant that cam recycle any kind of plastic. His plant is named MBA Polymers, at least according to google. In 1992 Mike Biddle known as a plastic engineer, set up a lab in his garage in Pittsburg, California. From here he began experimenting with complex-plastics recycling, borrowing ideas from such industries as mining and grain processing. Biddle has developed a patented 30-step plastics recycling system that includes magnetically extracting metals, shredding the plastics, sorting them by polymer type and producing graded pellets to be reused in industry. This process that takes less than a tenth of the energy required to dispose of plastics and waste, makes virgin plastic that is put back into our toys, electronics and every day appliances.



He says: "I consider myself an environmentalist. I hate to see plastics wasted. I hate to see any natural resource – even human time – wasted.”

Who Says Electric Cars Cant be Cool?

Tons of people think that electric cars will not be able to hold a major appealing factor in a world of gas powered super cars. Well, to all those people who think electric cars cannot be cool, they should look into the "Inizio electric super car." After all of our class talk about recycling and helping out the environment, i was curious in finding an automobile that would actually catch the eye of any individual who were to see it out on the street. The result was this electric super car. If the world wants to start doing better in the automobile industry by reducing their emissions, they should look into the technology put into the Inizio. I found this really interesting because i have always been a big fan of cars (specifically muscle and super cars) since a very young age. This car could be a start to a type of "car taste" that could spark a new public interest in these types of cars. What would be better than an electric car that could beat the rest, not only on the quarter mile or race track, but beat all other cars in terms of helping the environment?

Great Pacific Garbage Patch



After thinking about how much stuff ends up in landfills and as litter on the sides of roads etc., I was curious about how much trash ends up in the ocean. Upon further reading, I learned about the Great Pacific Garbage Patch. It is an area of litter found between Hawaii and California in middle of the North Pacific Subtropical Gyre.

Indiana's E-Waste Recycling Law

Our selected reading from The Story of Stuff over the possible risks of producing electronic items such as laptops and cell phones greatly sparked my interest.  Modern America has become immensely consumed by the use of cell phones, laptop computers, televisions, and other electronic products.  Annie Leonard highlights the issue at hand: the increase in demand for electronic products directly correlates with an increase in hazardous compounds released during production poisoning workers and surrounding communities in the process.  When I began doing more research on this topic online I discovered that while production of electronics presents significant environmental risks that have yet to be fully resolved, there is an even more serious issue at hand.




With new versions of electronic products being released more and more frequently, consumers have the enticing temptation of ditching their old product and upgrading to the newer version.  The question becomes, what happens to these electronic products that are no longer wanted? The answer is that these products become e-waste.  Controlling e-waste has become a key focus of state legislatures in recent years as electronics continue to become more widely used and discarded.  In May of 2009, Indiana became the nineteenth state to pass a law that creates a statewide e-waste recycling program.

e-waste.jpg


There remains no national law in place to regulate e-waste; and until this changes, Indiana hopes to remain a leader in this movement of safe disposal of electronic waste. While Indiana's E-Waste Program is one of the better proposals among states that have enacted similar movements, e-waste will continue to present serious environmental and health hazards until more strict regulations are established at the national level.  Proper e-waste disposal and recycling is a very serious concern and should be treated this way.   Our government needs address this issue sooner rather than later before serious irreversible damage is done to our ecosystem by the hazardous toxins which could be released by these discarded electronic items.

We Waste More Than We Should......

 Out of the many elements that gets thrown out on a daily basis, the one form of trash that should not be wasted, as much as it has been in recent years, is food waste. I have always been taught growing up to never waste any food during a meal, but apparently the same does not go for consumers in many societies around the world. In most cases, we don't even realize the major impact a half of a sandwich, our dinner leftovers, etc. can cause when an individual just throws it out. Especially here at DePauw, i have seen people throw food out and say things like, "oh its not big deal, I'm full but don't want to carry it back to my dorm." Other things people would say are, "I'm not going to worry about it, i have plenty of food back in my room if i get hungry later on." The fact is that many people, even here on DePauw's campus need to better their habits when it comes to food and reusing/ saving their food that they consume on a daily basis.   

Worlds Largest Landfill

The Great Pacific Garbage Patch

As I was browsing the web about the World's Largest Landfills, I came upon numerous results stating that the largest landfill is located in the Pacific Ocean called the Great Pacific Garbage Patch. With the world producing over 200 billion pounds of trash per year, 10 percent of that ends up in the ocean. This statistic really caught my eye, obviously affecting the marine life in the oceans. Some areas in the worlds oceans are taken up by a 6 to 1 ratio plastic to plankton life. Some parts of our ocean system contains 46 thousand pieces of floating plastic per square mile. Seventy percent of the plastic floats to the bottom of the ocean floor, which will affect the plant and marine life in the ocean. About eighty percent of the plastic in the oceans comes from land. So that means that humans are freely letting the plastic get into the ocean ecosystem. If the trash is not coming from land, most of the other sources would be from private or commercial ships, fishing equipment, oil platforms and spilled shipping containers.

These statistics make me cringe, knowing that every day trash is adding up more and more. I think the way to change this problem is to let the public know. I think the media sometimes tries to hide these scary statistics from the public. If the world knew, I think it would better improve our society as a whole. People would take into consideration where and how to dispose trash.





Why do some recycling facilities accept certain materials, while others don't?

Now that we have been to 4 different facilities that deal with waste, I started noticing how each place was a little different about their rules for what they do and do not accept.  While I do understand they vary because of market demand and fluctuating prices, I find it hard to keep track of who takes what and why.  I got curious, and looked up what Indiana's policy was on what they accept to be recycled, and I was pretty shocked.  Their list is fairly lengthy and contains some items that some of the facilities we visited would not have wanted.

Here is a link to the article: http://www.in.gov/idem/recycle/2345.htm

They accept basically every type of glass to be recycled, when the local plant owners tended to agree that breaking down glass to recycle creates a sand film that shut will shut down the machine.  They also accept saw dust, but when we visited our first facility that collected recyclables from the community said that they have no idea what to do with sawdust, and just end of land filling it.

Improving Your Home Efficiency


One of the easiest ways to reduce your impact on the environment is by improving the efficiency of your home.  This would decrease your carbon emissions, and even save you money on your electricity bill.  There is an endless amount of information available online, and endless amounts of home improvements as well.  When I googled it, hundreds of helpful websites popped up.  Here is a list of simple upgrades that can help you improve the efficiency of your home.

1.  Make sure your walls and attic are well insulated.
2.  Upgrade or replace windows.
3.  Plant shade trees and shrubs around your house.
4.  Replace an older furnace with a high efficiency system.
5.  Improve the efficiency of your hot water system.
6.  Replace incandescent lightbulbs with compact fluorescent lamps.
7.  If you buy a new refrigerator, don’t leave the old one plugged in.
8.  Take advantage of new tax incentives to improve your home.
9.  Schedule an energy audit for more expert advice on your home as a whole.

This list was taken from http://greenhomeguide.com/know-how/article/9-ways-to-make-your-home-more-energy-efficient and the website goes into further detail if your interested in learning more about how to improve the efficiency of your home.  Obviously this list is short, and there are many other things you can do to reduce your impact on the environment.

Cradle to Cradle, the real ideal model


One of the most important concepts with which we culminated the class the other day was the concept of waste equals food or in other words the cradle to cradle mentality. From my point  of view in order to finish or achieve a perfect cycle of matter instead of the linear one that stops at the landfills or incinerators, we need not only to recycle more, but also to design a new operating system that revolves around the natural world. We need to aim towards green engineering for the mere reason that any of the models that we have currently are considered a long-term waste disposal system: the incinerators (if we take into consideration that toxic emissions are unsustainable too in the long-run), and the landfills are represented as an infinite waste accumulation. Our current system is based from the fundamentals of the Industrial Revolution, and back then they didn’t really stop to think about the long-term consequences of production in the future, since the only thing that mattered then was producing in large quantities, creating new stuff and newer inventions without restrictions, in order to progress. Now however, to make real progress we should start designing and envision a system that doesn’t lead towards an entropic world, but  towards the sustainable cycle that we talked about at the beginning of the month.




Sustainablity: The Cradle-to-Cradle Perspective

The Cradle-to-Cradle Framework does not reach for sustainability as it is typically defined. Discussed at length in various papers, books and other venues, environmental sustainability in the industrial sector is popularly understood as a strategy of "doing more with less" or "reducing the human footprint" to minimize troubling symptoms of environmental decline. From an engineering perspective, conventional sustainability too often suggests retrofitting the machines of industry with cleaner, more efficient "engines" to secure ongoing economic growth. But this is not an adequate long-term goal. While being eco-efficient may indeed reduce resource consumption and pollution in the short-term, it does not address the deep design flaws of contemporary industry. Rather, it addresses problems without addressing their source, setting goals and employing practices that sustain a fundamentally flawed system.
The Cradle-to-Cradle Framework, on the other hand, posits a new way of designing human systems that ultimately can solve rather than alleviate the human-created conflicts between economic growth and environmental health that result from poor design and market structure. Within this principled framework, which is based on the manifested rules of nature and re-defines the problem at hand, eco-efficient strategies can serve a larger purpose.

"Roses are red, lipsticks have lead"

After doing my presentation in class on the production of waste, I was drawn to a quote Annie Leonard included in her book: "Roses are red, lipstick has lead". The idea that lipstick, a product most women use daily, contained any sort of harmful materials astounded me. So I researched into this issue more only to find a report made by the FDA that found of 20 lipsticked tested--in an experiment-- all 20 contained some form of lead. The report then goes on to say how the testing was expanded to 400 lipsticks sold in the Untied States, and the results concluded that the "lead concentration" was averaged at 1.11 ppm. But the FDA concludes that this level of lead in lipsticks, is not any sort of safety concern. The information and conclusion that this report gives leaves me uneasy, because although the FDA states that the current levels of lead in lipsticks are not harmful I worry for a future where they are.

Final Field Trip

Today we went on our last field trip to Republic's recycling plant. I thought this plant was very interesting. The tour that Mike gave us was awesome. We were able to go right up next to the assembly line and see the work at hand. I learned a lot of interesting stuff about the plant as well. With the economy being as down as it is, Republic was given 3 million dollars to build their recycling plant and to "do the best they could with what they had". With the amount of money that they were given the plant has exceeded all expectations. With the plants success, Republic has gone back to the drawing board to hopefully put more money into the plant in the near future.

How other countries deal with household garbage?



After two weeks of class, most of us have got an image of how we deal with our trash and where our trash goes. Though America has already got a good system dealing with trash, we can still look at how other countries deal with trash and learn from them.

Blog 2: UpCycling a Term Coined in 1994 is...


Upcycling is a hip term for taking waste materials and turning them into new, useful, quality items. Items that most of us would have never considered as worthwhile to keep around can actually be turned to new products. Websites like pinterest have been inspiring Internet users since 2009. Before you throw away that fruit punch carton, that old map or your T.V. get in touch with your crafty side and come up with a way to reuse that item or if you need help there is always the world wide web at your fingertips loaded with inspiration. Websites like Esty is filled with users that upcycle items and even make a profit because people, green at heart or not, find these items inventive and sentimental. Upcycled items are keeping trash from the municipal waste stream, so less waste means less energy used for waste pick up and less waste going to incinerators and landfills where overall less toxins are emitted into the environment.

Walmart Plans to Buy More American-Made Goods - NYTimes.com

Apropos of our discussions regarding the global economic system, local economies, Walmart, and the complex supply chain of consumer goods, I just saw this in today's New York Times:

Walmart Plans to Buy More American-Made Goods - NYTimes.com

In the last decade or so, American manufacturers have moved operations to China, Bangladesh, Vietnam and other lower-cost countries as they try to meet retailers’ strict cost requirements. However, recent consumer interest in American-made goods, rising labor and energy costs overseas, and pressure to get merchandise from the design phase into stores within weeks rather than months have renewed interest in manufacturing in this country. 
The just-in-time system of lean retailing plays a role in Walmart's shift (a minor one, of course), according to the article. 

Discussion on Walmart?  Are they moving in the right direction, or is there in principle no way for Walmart to operate its supply chain ethically while still being Walmart?

Bioremediation: Answer to Reduce Leachate in Landfills?


One element in class that drew my attention was learning about landfills and the major concern of environmental hazards they produce due to leachate. Because of this, i was curious in finding an answer to the leachate problem that would help this contaminant be a thing of the past. "Leachate" is any liquid that drains from land or stockpiled material and contains high concentrations of undesirable elements developed from the material that it has passed through. this problem is what allows people to question landfills especially in highly populated areas. These populated areas could be subject to water supply contamination, thus being harmful for the people who drink the water.  


After surfing the Internet for a while, i came up on a process called Bioremediation. This process involves the use of micro-organism metabolism to remove pollutants. Bioremediation involves treating the contaminated material at the site, thus reducing/ eliminating the chemical impact that the contaminant may pose on any location in question. After reading the articles i posted below, i could not help but to wonder why this process is not heavily used in all landfills around the globe. The use of the micro-organisms is a method that not only holds a natural effect on the environment that has been contaminated, but, it is a cleaner, cheaper, and safer way to rid these toxic contaminants within landfills. Therefore, i believe bioremediation allows the process of waste management (in landfills) to be a better and more environmentally friendly method of getting rid of trash in populated areas. ultimately, providing an answer to solve the problem of leachate in landfill designated areas.

Nike Recycled Jerseys

When you think of Nike jerseys, you wouldn't expect that they are made of 96% recycled material.  This video shows the process of transforming recycled plastic into professional teams' uniforms.  This is the first time I've heard that Nike uses recycled material in their products, and I'm surprised they don't advertise this heavier.  Nike's reputation was tarnished when they employed children in overseas factories, so advertising the eco-friendly products could help turn this reputation around.

Debate of Landfills versus Incinerators

Today in class we discussed our stances on the rising debate over whether the nation should burn trash at new generation incinerator facilities known as waste to energy plants or continue to use the method of burying it in landfills which has been the prevailing strategy in the past.  I was previously leaning towards sending a majority of our trash to these plants but have now shifted my stance.  I believe that waste-to-energy plants provide significant advantages which landfilling can not match, causing me to say that all waste produced should be sent to these facilities.

A major concern of those who oppose the incineration initiative deals with emission of disease causing dioxins and other pollutants that can potentially enter the food and water supply.  This issue which may have had legitimacy in the past has been nearly entirely eliminated with the improvement in modern technology.  The federal government has issued a requirement that all ash be tested for toxicity before it leaves the plant.  Modern plants more than meet requirements, and as a result, all threats of hazardous material being emitted are essentially negated.

Another prevalent argument held by opponents of incineration it is that it is a significant waste of energy; the low colorific value of burning waste to energy makes it ultimately and inefficient method of trash disposal.  

A major reason that building of incinerator plants are shut down deals with discouragement or composting efforts.  This is in fact a false misconception.  Waste-to-energy plants hold that recycling is an essential part of the energy conservation process, and that they are ultimately in competition with landfills.  Recycling is by far the most efficient method of waste management, but expecting everyone to recycle considering the cost of doing so, is unrealistic.  

Compared to landfilling, incineration offers considerable energy conservation benefits.  Until our country becomes much more efficient at recycling and can progress in the zero waste initiative, these plants offer us the best possible solution to waste disposal. 

Week in Review


After taking field trips to Oscar Winski, Ray's Recycling, and Convanta Energy, I further understand how the waste system works in our society today. I think that these three businesses gave us students a better context and eye opening experience. Reading about this type of stuff on paper does not do the justice of how the waste system works, whether it is recycling or decomposing. 

At the Oscar Winski facility, I thought it was neat to see all the different types of materials separated into boxes. It made me realize all the different types of metals that are used to make products. Some of the metals are more rare than others resulting in a greater demand. I thought the electronic waste system was very cool. It showed me how our society is changing over time. I anticipate in the future we will switch to this type of recycling because it seems to be more of an Eco friendly system.

Ray's Recycling gave me a glance into what recycling centers around the world work like. They use a line in order to separate cans, bottles, and paper. These workers endure many poor conditions in their work day but that does not keep them from working at Ray's. This has made me in the past couple days think more about throwing away my trash. Humans need to be more understanding of the affects that placing whatever we want into the trash. In the end, it causes harm to our society and makes for more work in the shops.

Covanta energy was an eye opening experience for me. I have never been to an incinerator facility before and I thought it gave me an understanding of how we get rid of the trash. Although there is much debate over whether these are Eco friendly and the right thing to do. I believe it is wise if used in the right way which is putting the trash that can not be recycled or discomposed.

Recycling Myths


            So far, after being in this class for just under a week, I have already learned so much about the materials economy and waste management.  After traveling to different businesses and locations on our field trips, one specific area kept sticking out to me as I wondered about where our trash really goes, and what we as a population can do to help improve our planet.  Recycling.  Now, I know that recycling alone can not solve every problem, but it is a big part of it, and I wondered about the different myths and false beliefs about this process that people held, and what I could do to help set it straight!  I found a website that focuses on these "rumors" of recycling, and the real facts behind them. 

First Week in Review

Going into this first week of class, I really had no idea what to expect. After going through the first week, the class was much more interesting than what I ever thought it was going to be. Throughout this first week, we an interesting video on where "stuff" comes from, the process in which the "stuff" is produced, and the effects it has on the environment and people that run the cycle. One of the examples that the video brought up was the $4.99 mini radio. The narrator stepped back and thought about how the little radio was produced from the very beginning. She explained the mining of the precious metals and plastics that it was composed of, and mentioned how the workers that put together the radio sacrificed their lives in order to make a few dollars a day. This idea got me thinking about all of the little items in stores, and larger ones for that matter, should be way more expensive than what they are today.  After we watched this video, we were assigned our winter term project. I was assigned the theft of the Hub's silverware and plates with Joe Hennessy. This seems like a very interesting topic and we have begun researching many different ideas about the products. We also took two field trips this week. The first one we took was to a recycling company in Lafayette, IN. We visited Oscar Winski's plant and were given a tour to experience the process in which the trash goes through from when it is dropped off, to when it is finally recycled. On Wednesday, we visited Ray's Recycling outside of Indianapolis, and Covanta Energy. I was very excited to see Covanta Energy. When we arrived it was clear that Covanta was the largest facility we had visited.

This was a cool photo that I found that explains the process that the trash at Covanta Energy goes through from when it reaches the tipping zone, to when it is finally recycled. I thought it was very interesting to learn that Covanta Energy creates its own electricity off of steam and does not have to purchase any electricity from the city. Not many companies in the world are able to do that. They also supply much of the steam to the steam line that runs through Indianapolis, which makes electricity prices for the citizens much cheaper. At every facility we went to the tour guides were amazing and I definitely learned a lot about the whole process of recycling. What does everyone think the most interesting facility was, and what has been the most interesting part of class so far? 


Scrap Metal Disposal

After visiting Covanta and Ray's, I wanted to do more research on the disposal process of scrap metal, especially stainless steel.  Stainless steel scrap is very important to the production process.  According to the Australian Stainless Steel Development Association, 60% of stainless steel is made up of recycled content.  This includes reclaimed scrap, industrial scrap, and new raw materials.  Stainless steel is also unique because during its lifetime, it can be returned to its original state without any breakdown of its mineral components.  Also, because it can be recycled so often, its long life span makes it a high demand material.  Depending on country and demand, recyclers will import stainless steel and other scrap and send them to mills- either domestically or internationally.  Lastly, the fundamental components of stainless steel- nickel, chromium, and molybdenum- are all crucial for the production process.  This means this incorrect disposal of stainless steel can have large effects to the production process.  Since stainless has such a long lifetime, the effects of under use or production will not be seen until decades after the decrease in use.  It is very important to recycle stainless so it can be used to its full utility.  In 2004, China utilized 900,000 tons of stainless steel scrap in its 2.8 million tons of production.
