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:

Learning from Meethotamulla

leave a comment »

A week ago disaster and tragedy struck Colombo’s Meethotamulla garbage dump. The images and stories depict a heartbreaking chronicle of poor management, environmental neglect and human misery. Thus far, the press has been busy pointing fingers at various government agencies and political parties for blame of the disaster. The more difficult truth is that all of us are culpable in the problem that led to the disaster at Meethotamulla. The root problem is our high-consumption lifestyle and the solid waste that it generates. The amount of waste is significant but it is largely out of sight to most of us. Meethotamulla has provided a painful wakeup call. There are now efforts underway in our community to assist families affected by the collapse of the garbage dump. These are important initiatives but the tragedy provides a broader teachable moment where each one of us can do something to address the root problem that led to the landslide.

All of us are consumers and our waste, whether at home or at work, is collected and has been added to the mountain of rubbish at Meethotamulla. To get a sense for our school’s waste generation walk up the gym approach road and note the smell and sometimes overflowing numbers of black garbage bags. We send an average of two wagon load of solid waste off campus every week. I suggest that an appropriate response to the tragedy is to look for ways that we can reduce the amount of solid waste that we produce at school and at home. In the following section I include some suggestions that are based on personal experience and experiments to reduce my own ecological footprint at school and at home.

Reducing Solid Waste at School

  • At OSC we have had an ongoing campaign get the canteen to use washable plates and silverware. The initiative started with the Recycling & Sustainability (Train to Sustain) service group but was taken up by Reefkeepers and eventually the Canteen Committee. The initiative took several years of active lobbying but the changeover in December 2016 has made a difference in reducing solid waste. There is still, however, work to be done. The canteen is still selling juice in disposable cups with plastic lids and straws. We need to move on eliminating all the plastics and using washable cups.
  • Thus far, we are not composting any kitchen or garden waste produced by OSC.  In 2015 a Grade 5 class exhibition group  investigated the idea of using a biodigester to deal with kitchen and garden waste. The R&S group agreed to fund it with money from recycled paper sales but that proposal has not been given sanction from the school.
  • Waste separation is an area that each one of us on campus can do a better job with. The feedback from the maintenance crew is that the OSC community is not separating items in the three categories of bins. This makes it hard for the garbage collectors to separate, recycle and thus reduce the amount going to the landfill.

Reducing Solid Waste at Home

  • Follow the three Rs (Reduce Reuse Recycle). Reduce what you consume and make every effort to not take or buy disposable items like plastic bags.
  • When you shop, use reusable shopping bags. There are even reusable mesh bags for vegetables that have been pioneered in our community by Rachel Jackson, Clover Hicks and Raina Lockwood. Reefkeepers will be selling these shortly. These efforts reduce the amount of single use plastic that you take home. Check out Rice and Carry’s innovative ways of reusing rice bags to help reduce disposable shopping bags.
  • Separate your waste at home. This is probably the single best thing that you can do. Wet waste from the kitchen can be composted. A study that I did of my home suggests that roughly 50% or more of household waste is wet waste and mostly compostable. Household composting is a viable option for most of us with gardens and, if managed correctly, will lead to reduction in solid waste and smelly garbage bags.
  • We have the facility to recycle cardboard and paper and PET plastic here at school and you are welcome to bring in items to us. We ask that any plastic bottles are cleaned. For parents and teachers, the R&S group can provide guidance on where to go to sell your paper and cardboard if you have large volumes. This waste actually pays and the R&S groups has built up a capital fund thanks to paper and cardboard sales over the past 12 years.
  • We collect hazardous and E-waste items such as batteries and printer cartridges. We are working with Dialog to give these items to them or recycling. The Orange lighting company takes back CFLs bulbs. Thus don’t mix these into regular garbage bags.

Meethotamulla was an unnecessary human-made tragedy but we can learn from the experience and do a better job so that we do not contribute to a future solid waste disaster.

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.

2017 Progress in Recycling & Sustainability

leave a comment »

In the second semester of the 2016-17 school year a new crop of students joined the Recycling & Sustainability/ Train to Sustain team. We find ourselves busy once again managing the regular collections and doing various outreach activities to enhance solid waste reductions on the campus.There have been several developments in the last few weeks:

  • We have purchased a new set of plastic bins (made by Arpico with recycled plastic) that are being trialed out in classrooms for paper collection. They were bought with funds that we earn from selling waste paper.

  • Our local scrap dealer who we sell our collected paper to has asked us to separate colored paper from other (white A4 & A3) paper. He is willing to pay more for unmixed paper (LKR 8 instead of LKR 6). For folder cardboard he is willing to pay LKR12 instead of LKR 10. These are the first price increases that we have seen in almost 10 years.
  • The group is keen to explore and invest in a biodigester to better deal with some of our campus’ food waste. Aprico seems to have the best model. We have the money and now we just need to secure permission and devise a plan for the unit’s management and maintenance.
  • Several OSC classes have been on field trips to sites related to Solid Waste management and recycling. On February 24th the DP ES&S class visited the Viridis Recycling plant (a facility featured in a past post on this blog). Student leaders Aashika, Ary and Sangmin were all able to join this trip and once again we came away with a new appreciation for the extent and possibility of plastic recycling here in Sri Lanka. On March 3rd the DP Geography class visited our Pelawatte scrap dealer and his larger sister shop in Battaramulla (see images above). They conducted a short study on prices and the economics of recycling. I am now in touch with the Central Environmental Authority‘s Waste Management unit and we are planning class visits there in the coming weeks.

Two Steps Forward in the OSC Canteen

leave a comment »

Last semester the Recycling and Sustainability/Train to Sustain group worked with the Reefkeepers service group on a joint effort to reduce the use the of disposable plates. Anyone who has been following this blog will know that problems with disposable items in the canteen has been a long standing issue that we have written and campaigned about (see posts in November 2014 and February 2017). At last the momentum built up and, with the support of the canteen committee and school administration, money was set aside to buy melamine plates and cups. The changes were made without much fanfare at the end of semester 1 and we have now seen significant reductions in solid waste generated by the canteen.

We still have a residual problem of the canteen supplying disposable plastic cutlery (and cups). We aren’t sure why this is happening given the investment in nice washable silverware. There is also the issue of drinks being served in disposable cups (with plastic caps and straws). Thus, as this goes to press we have new target to address to continue making the campus more sustainable.

Another development has been the implementation of a better waste collection system. In January 2017 the school maintenance department put out a new system to better segregate solid waste on campus. They have a three tier system for a) food b) paper and c) plastic etc. This waste is collected by the maintenance department and then given to the municipal waste collectors who visit the campus twice a week. The campus community is still having difficulty separating waste and we have noted that there is a need for a campaign to have people use the bins appropriately.

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.

Train to Sustain: A New Chapter for OSC’s Recycling & Sustainability Group

leave a comment »

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.

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.
