ISWA Roadmap for Sustainable Waste Management in Developing Countries

December 9, 2020

The International Solid Waste Management Association (ISWA) is hosting a virtual presentation on Sustainable Waste Management in Developing Countries on December 9.

Agenda

  • 5 min Introduction from SCS Engineers Vice President, James Law, Chair WGL
  • 40 min presentation from Professor Sahadat Hossain
  • 15 min Q&A (moderated by James Law)

Sustainable waste management is a major issue for both developed and developing countries. Even though source reduction or recycling is the preferred choice of waste management, over 70% of solid waste is openly dumped or landfilled globally. The availability of land/space for building waste management facilities (landfills, composting, recycling, and/or Waste to Energy, WTE) can constrain the decision making. However, we need to pay special attention to both the availability of land/space and the applicability of technology in a specific region (based on waste characteristics). What works for developed countries like the USA or Europe or Japan, South Korea may not be applicable to Asia, Africa or Latin American countries because of the waste characteristics. The webinar will present and discuss roadways for sustainable waste management in developing countries.

Accounting For Emissions in Solid Waste Planning

October 29, 2020

 

Reducing Short-Lived Climate Pollutants

The International Solid Waste Association – ISWA, published a comprehensive report completed by SCS Engineers for ISWA under the Climate and Clean Air – CCAC, on reducing Short-Lived Climate Pollutants. A CCAC Solid Waste Emissions Estimation Tool – called SWEET, was used to investigate waste sector emissions of short-lived climate pollutants -termed SLCPs, and other greenhouse gases – GHGs.

Data was collected where multiple waste management scenarios in Tyre Caza, Lebanon. Publications on waste management in Lebanon, including an Integrated Waste Management Plan and Updated Master Plan for the closure and rehabilitation of uncontrolled dumpsites throughout Lebanon, provided data that were used in this study along with updated information provided by Lebanon’s Office of the Minister of State for Administrative Reform.

Different management options for reducing emissions of SLCPs over the short- and medium-term. Comparing emissions reductions achieved by implementing a range of programs over a meaningful time horizon provide greater clarity of vision to see which strategies produce the most climate benefits and are worth a high level of effort and the commitment of resources to achieve.

Solid Waste Emissions Estimation Tool

SWEET is designed to be used by solid waste planning professionals worldwide. It allows some degree of flexibility in selecting key inputs, which gives it greater control and ability to reflect local conditions but adds a level of complexity that may be difficult for some users to navigate. While offering users control of some model assumptions, SWEET includes many calculations and assumptions that are necessarily fixed and can produce unintended results given the model’s limitations. In addition, the assignment of input data that appropriately reflects actual and expected conditions can be challenging, especially when there is a large amount of information to be considered.

The reports on solid waste management in Lebanon and Tyre Caza following the waste management crisis provided multiple sources of data that required evaluation and processing before being used in SWEET.

Supporting Changes to Modern Solid Waste Practices in West Africa

July 10, 2020

Building a better solid waste management infrastructure is a top priority for the City of Madison’s sister city, Kanifing, in The Gambia, Africa; and Wisconsin solid waste professionals are helping.

Watch the video

When Kanifing began placing municipal waste in an old quarry on the outskirts 40 years ago, it seemed like a good idea. Today, the 45-acre unlined Bakoteh dump lies in the residential heart of The Gambia’s largest municipality, Kanifing, and it’s causing problems for the community.

  • More than 300 garbage pickers sift through waste daily to pull out valuable recyclable materials.
  • These pickers often have children that are left to “play” in the garbage to pass time during the days.
  • Some pickers even live within the dumpsite. One man has lived at the Bakoteh dumpsite for 25 years.
  • Surrounding residents and an adjacent orphanage/medical clinic deal with continuous issues including odor, dust, mosquitos, and smoke from the frequent fires at the dumpsite.

The good news is that work is underway to modernize the solid waste practices:

  • The City of Madison donated 1,000 collection carts to help Kanifing clean up its public areas.
  • In the fall of 2019, the UW-Madison College of Engineering’s Remediation Geotechnics class evaluated potential next steps to close/remediate the existing 45-acre Bakoteh dumpsite.
  • Wisconsin solid waste professionals have been putting in the pro-bono time to help Kanifing build a comprehensive solid waste program.
  • Kanifing’s mayor awarded money to youth groups to recycle old tires to build more collection containers across the municipality.
  • New waste collection vehicles have collected waste from more public receptacles, and used in combination with continued waste collection by donkey carts, the expanded coverage of waste collection has helped to reduce waste in public areas.
  • The Kanifing Municipal Council (KMC) has increased tipping fee collection at the Bakoteh Dumpsite to provide funding to expand their comprehensive solid waste program.
  • The KMC is currently working on a large capital project to secure the Bakoteh Dumpsite with a brick wall. After hours, trespassers set numerous fires at the dumpsite by burning tires to retrieve the tire wire, which cost KMC a lot of emergency funds to control fires.

Get more background on what’s driving the need for action, meet the team of stakeholders working together to drive positive changes, and learn more about the progress they’ve made by viewing this video from your friends and colleagues at SCS Engineers.

If you’re interested in learning more Chris Jimieson is happy to help.

ISWA “closing dumpsites” initiative: status of progress – article and editorial published

May 29, 2019

The International Solid Waste Association (ISWA) has determined that uncontrolled dumpsites hold 40% of the world’s waste and that the world’s 50 biggest dumpsites (identified through a voluntarily survey conducted by D-Waste in 2014) directly affect the daily lives of 64 million people, equivalent to the population of France.

The ISWA reports (2014, 2015a, 2015b, 2016) showcase how eliminating dumpsites is an urgent issue, affecting local, regional, and even global health and the environment. Important findings indicate that 38 out of the 50 biggest dumpsites directly impact marine and coastal areas and can become sources of disease outbreaks and the release of wastes (particularly durable plastics) to waterways and the oceans.

Studies suggest that non-engineered dumps and uncontrolled landfills are the third largest source of global anthropogenic methane, a greenhouse gas about 25 times more potent than carbon dioxide (CO2), accelerating climate change. It is estimated that open dumps emit the equivalent of more than 20 million metric tonnes [tons] of CO2 per year. Without any action, it is projected that existing open dumps will account for 10% of global greenhouse gas emissions by 2025.

If open dumps instead were replaced by engineered landfills with state-of-the-art landfill gas collection and destruction systems, it would be like removing five million cars from the planet.

In 2018, ISWA’s Working Group on Landfill (WGL) developed a Task Force on Closing Dumpsites (TFCD) and presented its dump closure initiative as one of its flagship projects for the future at the United Nations (UN) Conference on Housing and Sustainable Urban Development – Habitat III.

Please read this important ISWA Editorial by James Law and David Ross on this significant issue. The editorial contains a link to the full article available on open access through ISWA’s Journal, Waste Management & Research here.

SCS Engineers brochure – Closing Dumpsites is also available.

Closing Dumpsites – Informative Brochure

October 23, 2018

An open dump refers to a land disposal site where solid waste is disposed of in a manner that does not protect the environment, is susceptible to open burning, and is exposed to the elements, vectors, and scavengers. Therefore, closing or upgrading open dumps to a sanitary landfill is a key issue for many communities worldwide.

In 1976, the passage of U.S. federal legislation known as RCRA pushed for the closure of open dumps and encouraged the development of modern sanitary landfills. In the 1990s, the U.S. EPA issued rules implementing such requirement. As a result, thousands of open dumps were closed.

The informative brochure “Closing Dumpsites,” is intended for many countries that are now beginning down the path to closing them with basic information of the process. Although U.S. dumps have been closed for many years with SCS providing post-closure and long-term care of these facilities, other countries can learn more about the long-term management of these facilities from our professionals nationwide by contacting us at .

These guys know what’s coming down the road, or floor, as the case may be. Do you?

September 14, 2017

These guys don’t want to miss Resource Management and Waste Diversion: Evaluating the Impact on Waste Management caused by the Changing Waste Stream Composition at WasteCon/ISWA 2017.

Solid waste management, and in particular sanitary landfilling, is being impacted by the waste composition evolution. One notable change is an overall decrease in tonnage. Reasons for the reduced quantity may be attributed to factors such as increased diversion of recyclables, increased diversion of vegetative organics, evolving diversion of food waste, changes to packaging, expansion of fresh organic foods lifestyle, expansion of fitness lifestyles, as well as other generational life choices.

Learn more about this topic and many others at the ISWA/WasteCon conference in Baltimore, MD.
