A Social and Environmental solution

Low-income communities are at the forefront of mismanaged plastic with waste management in the global south dominated by informal collectors. Despite their significance for the environment and the economy, informal waste collectors often face marginalization and are subjected to exploitation and price fluctuations which threaten their income. TONTOTON’s purchasing model allows for a reliable and consistent trading price per kilo for all types of plastic waste, establishing a novel market for low-value post-consumer materials which are not subject to market instability.

Although clean-up activities offer mitigation, as well as providing a tool for awareness, they are not an effective strategy for alleviating the plastic leakage problem. TONTOTON’s solution aims to both prevent plastic entering the environment through source-reduction as well as removing coastal deposition. Sorting of waste at a household level is an effective technique for reducing leakage.

Together with PET bottles and Styrofoam, we identified that the majority of mismanaged waste is associated with households due to ineffective solid waste management systems. TONTOTON’s household partner project stops this leakage at the source as well as encourages reduced consumption of these materials. Key villages in Vietnam and Cambodia are lacking any formal waste management at all, so without this solution the plastic would be discarded into the environment or burnt outside the houses.

waste management approach

The co-processing of waste has been recognized as a recovery operation under EU legislation


  • Conservation of non-renewable fossil fuels ​& natural resources:
    → Thanks to the use of plastic waste as an alternative fuel,​ there is no extraction of fossil fuels, limestone, or any other minerals.
    ​I.C.16 Basel Convention Technical Guidelines p.10

  • Reduction of CO2 emissions​:
    → Integrating cement kiln co-processing within an overall waste management strategy may offer the potential ​to reduce net global CO2 emissions relative ​
    to a scenario where waste is combusted ​in an incinerator without energy recovery. ​
    I.C.22 Basel Convention Technical Guidelines p.10​

    This solution enables the avoidance of open-air plastic burn and provides a greener solution for the cement industry.

TONTOTON’s Material Recovery Facility (MRF), situated in the heart of the polluted coastal city of Sihanoukville, Cambodia. The first of its kind in the country – plastic is either upcycled, recycled or utilised as an alternative energy source for a fully circular solution. TONTOTON’s collectors remove all mismanaged plastic from the environment, leaving nothing behind. Waste is brought the MRF for segregation into different sorting lines where HDPE, LDPE, PP and PE in good condition are reformed into new products through heat-processing techniques, PET is directed to a bottle-to-bottle factory, and degraded plastic is sent for co-processing.

The aim of upcycling the non-recyclable plastic is to support TONTOTON collectors by providing housing materials such as new durable, UV resistant roofs and walls. We will also create full traditional houses using low-value material for community development programs. Transforming polluted villages and supporting the people most affected by the plastic, now in a positive way.
