2018-19 R&S Service in Review

leave a comment »

Final group shot of the R&S Group for the 2018-19 School Year.

This has been an excellent year for OSC’s Recycling & Sustainability group. We enjoyed an excellent and enthusiastic team of students supported by fine student leadership from DP2 student Devin Amalean supported by Louis Gunaratne. There were several highlights:

  • We continued to provide a weekly recycling service to the community, taking in paper, cardboard and PET plastic. This is where the bulk of the group times goes to and we have a well-established relationship with our neighborhood scrap dealer. We bought used rice bags this year to put are recycled paper into and this made some of the process easier. Our earning are higher this year than a few years ago but the volume recycled is lower-we hope a result of lower consumption patterns (see graph below).

Accounts of the R&S Group looking back more than 10 years. We are recycling less volume of paper and cardboard compared to several years ago but we’re earning more money thanks to the change in value (and more likely the LKR exchange rate).

  • Energy use and renewable energy was part of the reason that we supported the introduction of a school biogas plant. This simple yet novel device turns wet food waste into useful gas for cooking. The R&S group funded the purchase and installation of the biogas plant (it was installed in October 2018). We utilized our nearly 14 years of funds raised from selling paper and cardboard to do this. (see past reflections for details).
  • On March the Recycling and Sustainability group sponsored a special OSC Environment Day. Aashika Jain had originally started this event off as a CAS project in March 2018. This year we collaborated closely with the Reefkeepers service group in the planning and execution of the event. The PYP environmental club also participated and helped out. This involved prior planning (see pictures) the focus, content and means (skits, talks etc.).

Madeleine & Devin starting off the 2nd annual OSC Environment Day on March 12, 2019. The event was a whole school assembly designed to bring attention to environmental issues with a focus on reducing solid waste on the OSC campus.

  • We produced a R&S T-shirt this year-the brainchild of DP1 student Divyanshu Thakur with support from the faculty facilitator and student leader. We printed 50 t-shirts and sold about 75% of them. The shirts feature a green footprint and the group’s name. Originally, they were supposed to have a message encouraging the community to reduce, reuse and recycle, but unfortunately this was left off on the design that was printed (!!). On Environment Day we were able to present a t-shirt to all of the maintenance staff that are involved with solid waste management. See Divyanshu’s blog reflection on the day to get an idea of the process.
  • This year several OSC classes made close curricular links with issues that the R&S service group is involved with. The DP1 Geography class conducted a neighborhood solid waste study (see post) and Camille-Anh and Jordan of the DP2 ES&S class visited both the Viridis plastic recycling facility and the E-Waste factory (see post). Those trips were learning exercises, but we also delivered OSC’s recyclables to be processed. Meanwhile Nehe and Shivani in DP1 ES&S were instrumental in running the burn tests on the biogas plant (see post).
  • The Recycling and Sustainability group has important support for the OSC maintenance crew. Mr. Imthiaz coordinates this and we have Rohan & Bandara who help drive the school truck with the recyclables every week. With the changed security situation after April we have to rely on 1-2 maintenance workers to help take the paper and cardboard to the scrap dealer on Pannipitiya Road. These folks play a key part in the success of the service group.
  • Finally. at the concluding awards assembly the R&S team of Grade 8 girls was recognized for their contributions to service at OSC. Here is the citation read by OSC’s service coordinator Ms. Linsday O’Sullivan.

“This team of MYP students go above and beyond the norm in their Community Service efforts. They work as a team, supporting and encouraging each other and their peers. All of them have done extra work, ensuring that the communities’ needs are met, even in weeks when Service isn’t officially running. They were all involved in the Environment Day assembly, demonstrating how to support green efforts at OSC. They are a force to be reckoned with as they Train to Sustain. The 2019 Community Service Award goes to Dasha Drechsel, Kevinja Karunaratne, Lexi Wiberg and Huirong Yang.”

Visits to the Pelawatte Scrap Dealer

leave a comment »

Class of 2020 DP Geography students learning about the economics of the scrap and recycling business at our local scrap dealer.

On Monday April 1st the DP1 Geography class visited our local scrap dealer to get a better sense of what happens to school recyclables.  This short field trip followed up a longer two week field investigation  into solid waste patterns in the OSC neighborhood (see separate post). The group of eight students took several bags of mixed paper as well as some folded cardboard. The scrap dealer is based out of an old shipping container on the side of Panipitiya road. Students were able to ask a series of questions and learn more about the economics of recycling from the perspective of this dealer. We also sold our mixed paper (12kg) and cardboard (5 kg) for a grand total of 146 LKR. Students also got a chance to speak with Matt Jackson, a patron and OSC community member. He outlined what he does in terms of collecting and sorting recyclables which are deposited at the dealer. He doe not take any money for his materials.

2019 Data

2018 Data

The class has updated the buying (and selling) costs of the materials that our scarp dealer deals with in. Some prices have climbed while others have decreased since we gathered the same data last year. These are purely based on what our dealer is telling us and we know from past studies that we could probably get better prices at other locations. Our goal, however, is to reduce solid waste and not to earn more money. We remain interested in patterns of recyclables and commodity prices.

OSC Neighborhood Solid Waste Study 2019

leave a comment »

Preparing to run a solid waste survey at a modern house east of the OSC campus.

The 2nd semester is a time of class field trips to various recycling and solid waste operations in the OSC neighborhood.  The DP Geography class is preparing to conduct field research in Sinharaja so as a trial they conducted a field survey of solid waste patterns in the OSC neighborhood. There were several stages to this operation:

  1. Taking a preliminary observation-based walk to assess the study area.
  2. Devising the research questions
  3. Creating an appropriate survey using Survey 123
  4. Preparing a base map using OpenStreeMap as well as new 1:10,000 data from the Sri Lanka Survey Department. Revieiwng and updating data on OSM for the OSC neighborhood
  5. Conducting the field work (over two lessons)
  6. Compiling, processing and graphing the data.
  7. Sharing the data in a poster, individual assignments and online (this post)

As a part of the project the class worked with a variety of maps to get a sense of their study area.  OpenStreetMap is a great source but most of the building have not yet been mapped. Previous classes of OSC students have mapped the school campus but the Class of 2020 worked to expand the area. The maps below show the progress that they made on this ongoing project.

 

CONCLUSION

The field study was completed after two blocks of data collection in the OSC neighborhood. Together the class was able to survey 26 different households near to the OSC campus. We have a much better sense of of our neighborhood though it would be good to continue the study and get more houses surveyed. There were a few conclusions.

  • Most residents are getting some sort of municipal solid waste pick up. 23 of 26 respondents(86.5%). Respondents mostly appeared satisfied with this arrangement abut several remembered times when the collection system had broken down in the past 2-3 years.
  • 23 of the 27 (92.3%) respondents are separating waste. This makes sense as it is now required by the municipality.
  • A few residents stated that they did weekly burns of leaves and paper. (3 of 26 or 11.5% households surveyed). However it seems, based on observation, that other items (Tetrapacks, plastic bits) are being mixed in with these burn piles.
  • Only a few households were composting (3 of 26 or 11.5% households surveyed).
