Profile - Amy Smith, MIT D-labs

Ms. Amy Smith is an instructor MIT's D-Lab which offers courses in Mechanical Engineering. But unlike the conventional engineering course or lab, Ms. Smith along with Ms. Bishwapriya Sanyal offer a course in which engineering students don't just learn the concepts of mechanical engineering, but go all the way to complete a product that addresses need of the under served communities of different parts of the world.

In a four-part course, the students start out ( in the "Design" part)learning about specific sectors of development that need to be addressed and the appropriate technology that can be applied. The second ("Development") part, is a combination of

• lecture, which talks about various aspects of design like affordability, sustainability, design for manufacture and assembly,

• Labs that offer experience on fundamentals like welding, circuit-boad design, CAD etc

• Case studies and field trips to understand the needs of the people to who this product will eventually be useful
• design review discussions to present and refine ideas of the product
  

The third ("Dissemination") part of the course focuses on brain-storming ideas to make the product that conceived by part-two to be "ready to roll", which includes making the product scalable, affordable and marketable. The fourth part executes what was conceived in part three.

In the process, her team has been successful in providing local solutions for local yet, problems local to a specific region as against trying to find a generic "one-size-fits-all" solution. The best example for this is offered by the following video of her presentation outlining a method of using sugarcane waste and biomass to produce a clean and efficient fuel thus providing a solution to the worst killer of children under five - household cooking smoke, but also to make the fuel at home using the abundant agricultural waste (this avoids cutting trees and cuts down on expenses in buying fuel) Truely amazing...and this is just one of the projects in MIT D-labs.

Saving paper, saving trees? A few answers

I have posted the same post on NGO Post and got a few answers

First is a video that gives an idea about the tree-to-paper relationship





So, the number is 1 tonne of paper = 17 trees. One of the articles from ecology.com says

"Unfortunately, the paper making process is not a clean one. According to the U.S. Toxic Release Inventory report published by the U.S. Environmental Protection Agency (EPA), pulp and paper mills are among the worst polluters to air, water and land of any industry in the country. The Worldwatch Institute offers similar statistics for the rest of the world. Each year millions of pounds of highly toxic chemicals such as toluene, methanol, chlorine dioxide, hydrochloric acid, and formaldehyde are released into the air and water from paper making plants around the world.

Paper making also uses up vast quantities of trees. But trees are a renewable resource, which means that once one is cut down another can be planted in its place. In fact, much of the wood used by paper companies in the U.S. comes from privately owned tree farms where forests are planted, groomed and thinned for harvest in 20 to 35 year cycles, depending on the tree species. Around the world, tree farms supply 16% of all wood used in the paper industry while the bulk comes from second growth forests. Only 9% of the wood used to make paper is harvested from old growth forests, which are impossible to replace because of their maturity.

Yet, while tree farms or plantations help feed the demand for wood, they can't provide the plant and animal diversity found in natural forests. Plus, according to a 1996 report from the U.S. Forest Service, the rate of harvest for softwood trees in the southern United States outpaced growth for the first time since 1953."

To summarize, manufacturing paper results in environmental degradation less because of cutting trees and more because of the method used. Though this offers a good idea about paper and its impact on environment, one must note that these are data mostly associated with US. In the Indian context, I found this in Myth and Reality about Plastic

Paper is not eco-friendly

We need to remind ourselves that making of paper and products consumes a lot of chemicals and requires a large amount of water and effluent problems are severe. Besides paper, unless coated with polymeric materials (or wax), cannot withstand wet conditions which are widely prevalent in India, particularly during monsoon periods. Paper making also consumes a lot of energy. In the Indian context the most serious problem is the availability of pulp. Environmental degradation has unquestionably occurred due to pulp manufacturing activities as commercial forestry, on large scale, is still a taboo. Padmabhushan Prof. M. M. Sharma (FRS) "

I have also stumbled upon information related to conservation in general, not necessarily related only to papers.

The story of stuff has a 20 min video about how consumption-minded lifestyle is killing the planet's life. Its a lot of talk (not necessarily cliche) with lots of statistics. But the core point is

- Recycling is important, but most of the products used are not recyclable and
- Lesser consumption pays off better in preserving environment.

Another link portrays people's consumption in the US in a unique pictorial representation rather than plain statistics. For a listing of companies all over India, involved in recycled paper products click here.

Is saving paper, saving trees?

I head an employee-driven CSR team in my company in India. I get numerous suggestions about saving paper by replacing paper cups with ceramic mugs and re-using papers printed on one-side for "personal" print-outs.

Though I don't oppose these ideas, I have my reservations about their efficacy. Following are the questions that have surfaced to my mind repeatedly.

- Trees cut for making papers have to be replanted because, we will run out of papers otherwise. We have no idea about the number of trees we are losing because of making papers. We also don't seem to be running out of papers. So, in the end we don't know if we are really causing a significant depletion of trees. May be we are, but is there data?

- The only way to cut lesser trees without compromising the supply of paper is to recycle paper. India seems to have a defunct system of recycling wastes. If we are indeed degrading environment by cutting a lot of trees, it is possible that this trend can be more significantly minimized by putting a system in place that recycles most of the paper wastes when compared to small initiatives in individual companies to save papers.

Of course we are better off taking these small initiatives irrespective of the status of recycling, but my concern is, we have no way to measure how many trees we end up saving. What if the contribution of 100 companies with an average of 100 employees actually comes to saving 5% of trees, while setting up a recycling plant that can recycle paper in the neighborhood (companies, homes, schools any and building where paper is used) can reduce the number of trees cut of paper by 50%?

Simply put, how can one make this initiative measurable? Is there a comprehensive and accepted research that can answer my questions?
