2016-17 Recycling & Sustainability Initiatives In Review

leave a comment »

The following graph highlights amounts of paper, cardboard and plastic recycled by OSC’s recycling & sustainability service project between 2008 and 2017. These resources are collected and sorted by students during our Thursday afternoon service block. We then take them in the school pickup to our neighborhood scrap dealer where the paper and cardboard is sold and weighed. We also collect plastic, batteries, cartridges, but we do not get paid significantly for these. Glass and metals are also collected but our numbers are not significant. Prices for recycled paper and card board have roughly stayed the same during this period (1kg of card board sells for 10 LKR and 1 kg of mixed paper sells for 6 LKR). While we have been working to recycle more of our school’s waste, we are also concerned about consumption patterns and are working to educate the community about reducing these levels. Nevertheless, there is a general decline in paper being recycled (perhaps due to lower consumption patterns when the school moved to an electronic, 1:1 teaching & learning environment in 2014).

This has been an important year in the work of the Recycling & Sustainability program. We had an infusion of new leadership in August and the new avatar Train to Sustain out a focus on bringing a wider circle of the community into the sustainability picture. This post is being published at the end of the school year as we look back at important landmarks and consider jobs that still need to be done in the future.

The land slide at the Meethotamulla Dump Site was a major environmental disaster in our local area. The media coverage was quite comprehensive and there had been a good deal of self- reflection on the deeper causes that led to loss of lives and property. At the time of writing it, is still unsure if the country is going to adopt the kind of policies that will address the solid municipal waste (SMW) problem and tackle it with aggressive efforts to reduce, recycle or compost what is left over.

At the school we made major headway with moving the cafeteria to be more sustainable. Significantly we eliminated all disposables: paper boxes, paper cubs, and finally straws. The credit for this is also due to the Canteen committee and Reefkepers who support the effort to eliminate disposables. The group continued to its weekly paper and cardboard collection and the results are shared above. This year we started to get paid higher rates when we delivered better segregated A4 paper and cardboard. Generally, the price was LKR 6 per kg but a few times we earned LKR 10 for paper and LKR 15 for cardboard. The school has a printing quote and we hypothesized that this has reduced overall consumption of paper. At this stage we can not comment on that since our data on paper purchased and consumed is incomplete.

We continued to build our relationship with Viridis, the country’s leading plastic recycling. The DP Environmental Systems & Societies class and several recycling leaders took a field trip to their site. Later Viridis set up a PET bottle collection point at the school. We have extended the option of recycling plastic bottles for the whole OSC community.

We still have work to do in the following areas:

  • General awareness spreading in the community.
  • Better use of the waste bins on campus. We have noted that, despite having three different bins, people are mixing what they throw away.
  • Overall reduction in the amount of solid waste generated by OSC.
  • Highlighting E-waste and doing a better job with recycling what we produce.

Several Important articles have been published about the Solid Waste crisis and ways to solve the problem in Sri Lanka. See the following references:

DP Geography Study of Pelawatte Recycling Operations

leave a comment »

The two recycling centers we visited (photo collage by Adrián Yáñez )

Solid waste is a global problem that is becoming difficult to manage. Most of us throw our garbage into a rubbish bin, but do we know where this garbage goes? On the 3rd of March, the DP 1 Geography class visited two recycling and scrap centers in the Pelawatte Area (near the OSC campus). They were relatively small places, but they gave the class an idea of what happens to the items that we throw away.

Solid waste management is a problem that Sri Lanka is facing, and there is only a small group of people who are working to recycle some of the items we throw away. In Colombo itself, 700 tons of garbage is collected each day (Roar), which is 58.6% of the total garbage collected in Sri Lanka (Sunday Times). To the majority of us, this value may not concern us, but where does this garbage go?

In Colombo, the garbage collected has historically been dumped at the Meethotamulla landfill, which is located 30 minutes from OSC, and has now become unusable, because of the various environmental hazards caused by the large amount of garbage dumped there. The problem in Sri Lanka is that the majority of garbage collected is not separated. Therefore it cannot be effectively recycled or disposed of. Based on a study conducted in 2012 by the Central Environmental Authority, 54.5% of the waste that is collected is biodegradable, which means that they can be composted (CSECM). If people were to compost this biodegradable waste, half of the garbage at the landfills would have never even be there. Separation is the key.

The people at the recycling and scrap centers we visited are examples of environmental heroes, who are not given the credit they deserve for the work they do. The picture below is the first recycling center we visited. It was a small place,but there is a lot of cardboard stacked out in front. All of that will be recycled. If this center was not there. That cardboard would have ended up at a landfill (or been burnt). Inside the the recycling center there were plastics, glass (bottles), and scrap metals which were all being collected to be recycled.

The people who own centers like this, are not recycling materials because they want to save the environment, instead they are doing it for an economic reason. They are able to make money off recycling materials, and by doing this, both themselves and them and the environment are benefiting from it.

Solid waste disposal is becoming a huge problem that needs proper management. A step each of us can take is separating our biodegradable waste from the rest, and compost it. This would reduce almost half of the garbage that is collected from us, and in turn reduce half of the garbage that is dumped in a landfill. The next step is recycling items such as paper, and plastic. By taking these steps, solid waste would not be such a large problem.

Canteen Sustainability Initiatives…again

leave a comment »

Waste disposal is significant concern both locally and globally. Articles in the Colombo-based Sunday Times as well as globally-oriented Guardian frequently highlight this negative aspect of our consumer culture. At OSC we are not immune to the problem and our school generates a significant amount of solid waste, especially in the canteen. In response to this challenge several groups have started an initiative to help the OSC canteen become more sustainable.

The main sustainability issue in the OSC canteen is the high volume of disposable items that are used and the poor separation when meals are finished. Most students are now using disposable cardboard boxes and plastic ware to eat their lunches. Drinks are served in disposable cups. In the secondary school students are eating in a number of places on the campus. After single use containers and plastic ware are thrown away. At the time of disposal there is no separation and thus almost every bin on campus has mixed waste of plastic, food scraps, paper and other items. Aside from this being an issue of health and safety (think of rodents, ants etc.) the mixed waste is virtually impossible to separate recyclables from. OSC’s waste is given to the municipal waste collectors in numerous bags of mixed, smelly waste. All in all, it contributes to an extra large ecological footprint for our OSC community. In a school where we emphasize the values of global citizenship the current situation with waste is an embarrassment.

The issue of disposable items was initially raised by the Recycling and Sustainability service group in 2014. Despite a study of the issue and suggestions for trying to tax disposables there has been little progress and the waste problem has festered. Since then then other groups have become interested in addressing the issue. The PYP Science activity has taken a lead in the primary school on waste issues. Reefkeepers, which draws attention to pollution of marine environments, is actively involved in pushing our community to address the issue. They made a presentation to the OSC Canteen Committee seeking support in addressing the canteen waste issue. In the past the Committee has focused on menus, diet and hygiene but is now considering sustainability issues.

To address the problem with disposables there is a clear way forward and the Canteen Committee is working to enable this. Simply put, the canteen needs to have all washable, reusable items (plates, cups, silverware). It is proposed to use washable melamine dishes with the OSC logo marked on them. This means an investment in new items and a dishwashing machine to enable quick washing and the ability to serve the school community. It also means that we need to rethink where people are eating canteen food on the campus. As of their last meeting, the Canteen committee had approached the SCN and school to allocate money for these investments. The response has been favorable and the plan is to roll out the new items at the beginning of the 2nd semester.

Simply bringing in new washable dishes is really only just the beginning of addressing the issue of OSC’s solid waste and broader sustainability challenges. Ideally we need to raise the awareness in the whole community on several areas where we can make a difference. With the support of the SGA, PSGA and the school administration the various service groups hope to draw attention to the role of individuals in helping OSC be a more sustainable community. Stay tuned for further developments.

OSC’s Recycling and Sustainability group at the beginning of the 2016-17 school year. This new chapter of the 12-year-old group is called “Train to Sustain.”

In the 2016-17 school year the OSC Recycling & Sustainability service group is once again taking on a range of environmental issues at the school. This is the 12th year of the service group and it continues to benefit from a clear mission to reduce the school’s ecological footprint and able student leadership facilitated by faculty guidance. Articles in the Colombo-based Sunday Times as well as globally-oriented Guardian frequently highlight this negative aspect of our consumer culture. The service group seeks to address these issues and work with other members of the community to reduce harmful activities and better inform the community about sustainable solutions.

Train to Sustain is the new chapter of the OSC Recycling & Sustainability service group. In the words of the new batch of student leaders “Train to Sustain strives to not only train ourselves on investigating potential solutions for reducing the ecological footprint in school, but also to train the school community (students, faculty, support staff & parents) on how they may do their part to aid our service, their school and Sri Lanka itself. Recycling has been our role but sustainability is our goal.”

Our 2016-17 service leaders include Aashika Jain, Aryaman Satish and Sangmin Kim. See our Facebook page for more information on the Train to Sustain chapter.

The State of Plastic Recycling in Sri Lanka: A Case Study of Viridis

leave a comment »

Plastic waste brought from Hikkaduwa for recycling at Viridis.

Plastic waste brought from the beach town/ tourist hub at Hikkaduwa for recycling at Viridis.

Plastic remains one of the single biggest and intractable solid waste management challenges in Sri Lanka. One doesn’t have to look too far to see plastic waste dumped along roadside or smoldering in small neighborhood fires. Currently, the Sri Lankan government as a part of their effort to improve recycling and resource management has been slowly trying to ban more of the less degradable plastic (CEA). The issue was covered by the Sunday Times and other news organizations (see links below). However, annual plastic consumption is increasing in Sri Lanka and  is set to increase from 6kg to 8kg per capita (Sunday Times). Waste management strategies not able to fully deal with the existing amount of plastic solid waste so what happens when the amount increases? This short post will look at the basic economics and geography of what is being done by a plastic recycling factory in the OSC neighborhood.

One of the largest plastic recycling companies in Sri Lanka is Viridis Pvt. Ltd. They have a fleet of 6-9 trucks that gather plastic from the most densely populated parts of Sri Lanka (from Anuradhapura in the north to Katharagama in the south). They currently buy plastic at around 20 LKR/kg but it fluctuates depending on petroleum prices (two years ago it was 40/kg). At the moment, petroleum prices are low and virgin plastic is cheap. Thus, the price for recycled plastic is relatively low. The global price for a unit of plastic has fluctuated as from 86 to 274 LKR (0.6 – 1.9 US$). Viridis collects most types of recyclable plastic such as PET bottles and higher grade plastics (buckets, toilet seats etc.). They used to collect plastic bags, but it is no longer cost effective.

OSC’s DP Geography class visited the Viridis recycling plant as part of their Patterns in Resource Consumption unit. They were joined by several members of the Recycling & Sustainability group. In fact, student leaders Nandini Hannak and Nisala Shaheed along with their faculty facilitator Ian Lockwood had made a preliminary visit in December (see their blog posts linked below). Viridis’ manager Buddhika Muthukumarana took us on a tour to show us the steps of sorting, clearing and palletization that happen in the process of recycling the plastic.

The key to plastic recycling seems to be in the economics of production and collection. At the moment the price of petroleum is low and virgin plastic (which is a byproduct of the petroleum refining process) is at one of the lowest levels (see these links: PN and FT). Thus, the price for recycled plastic has gone down significantly to the point that it is hardly a viable process to collect, clean, chip and sell it. After the eye opening tour we were left to ponder ways to consider improving the recycling business while at the same time discouraging wasteful use of plastic in Sri Lanka and other places. A key step would be to get the producers of plastic to have a larger role in the recycling or substitution of their materials. At the moment they produce an abundance of disposable items but play no role in helping society to deal with the waste! Surely this has to change as part of a broad-based solution to address solid waste challenges that Sri Lanka faces.

2014-15 Recycling & Sustainability In Review

leave a comment »

The following graph highlights amounts of paper, cardboard and plastic recycled by OSC's recycling & sustainability service project. These resources are collected and sorted by students during our Thursday afternoon service block. We then take them in the school pickup to our neighborhood scrap dealer where the paper and cardboard is sold and weighed. We also collect plastic, batteries, cartridges, but we do not get paid significantly for these. Glass and metals are also collected but our numbers are not significant. Prices for recycled paper and card board have roughly stayed the same during this period (1kg of card board sells for 10 LKR and 1 kg of mixed paper sells for 5 LKR). While we have been working to recycle more of our school's waste, we are also concerned about consumption patterns and are working to educate the community about reducing these levels.  Nevertheless, there is a general decline in paper being recycled (perhaps due to lower consumption patterns as the school moves to a electronic, 1:1 teaching & learning environment).

This has been a good year for OSC’s Recycling & Sustainability service group. In fact, this is a milestone year-the 10th that the group has been functioning! This school year was marked by strong student leadership and smaller but more efficient student numbers.  The group continues to occupy itself with managing recycled paper for the campus but we also delved into advocacy this year. Here is a quick review of activities and issues:

  • We worked with the canteen on trying to reduce the usage of disposable containers that are used for snack and lunches. We had initial success with this and consumption of disposable boxes decreased. However, after some time, it jumped back, highlighting several issues.
    • Firstly, what is driving the problem is the dearth of appropriate washable containers and cutlery in the canteen.
    • Secondly, there is wide spread apathy amongst students about using disposable materials. Our student leader Nisala has come up with further proposals to deal with this modeled on his observations and ideas from seeing the way that ASB handles solid waste (including food) in Mumbai.
  • In terms of amounts recycled our data shows that the total volume is going down. At the moment we don’t have exact numbers on how much paper was consumed but my guess is that it is less. This is likely because the school is moving to do much more of its communication electronically. This year, for example, student reports were all given out electronically. The business office has promised to share data on paper consumption that will either support of refute this hypothesis.
  • Students used Managebac to do their service reflections this year. Other than simply talking about what they were doing in the activity we emphasized reflecting on broader learning and trends in solid waste issues in Colombo and beyond.
  • In April several of us accompanied the PYP Grade 5 class on a visit to the large Colombo Municipal waste dump located near Dahampura. We were able to observe dozens of truck coming into to dump unsegregated solid waste. With the support of a scientist from IWMI the students collected water sample from nearby ponds and ran basic water quality tests on it. They have approached OSC’s administration to get a bio-digester (made by Arpico) to handle our food waste. The R&S service group has committed to supporting this with money raised from paper and cardboard sold over recent years.

We close the year with an acknowledgement that there is much, much more to be done. The solid waste crisis seems to get worse here (see news articles below) but we believe that our efforts are beginning to address issues both from a consumption and recycling point of view.

March 2015 group shot of the Recycling & Sustainability activity. (Below) Nandini, Nisala, Yoon Jae and Nishant getting a typical Thursday afternoon session going.

This week marks an important point in the service calendar. DPII (senior) students are about to step back from leadership positions and turn over the reins to younger students. In the Recycling & Sustainability service activity Yoon Jae Hwang and Nishant Matthew from the Class of 2015 have both served the group with distinction. They have led from the trenches and modeled excellent approaches to achieving the group’s mission of reducing the school’s ecological footprint. Aside from managing the weekly recycling rounds and paper/cardboard sales they have helped younger students with guided reflection. We wish them well as they step back, prepare for exams and get ready to move out into the world. We are fortunate to have Nandiini  and Nisala from the Class of 2016 ready to sep into Yoon Jae and Nishant’s shoes. Both Nandini and Nisala have already served in the R&S service activity for several years and bring their own  strengths and ideas to the group.

Borrowed form Mr. Lockwood's recent blog post. OSC recycling in action (from the top): Students in the Thursday afternoon R&S service activity collect and sort paper, cardboard and other materials outside the recycling room near the gym. DP Geography students weigh and sell cardboard to our main scrap dealer buyer who will resell it for recycling in India. DP R&S student leaders Nisala, Nandini and Nishant work with younger students on a reflection at the end of the Thursday service session. Data about patterns in consumption and recycling is gathered and analyzed as a key part of this activity.
