SCG-DMCR Litter Trap: SCG’s Innovative Solution to Marine Waste Problems

“Conserve and sustainably use the oceans, seas and marine resources for sustainable development” is one of the 17 UN’s Sustainable Development Goals (SDGs) that serve as a framework for global development efforts after 2015. The concept was reinforced through government, civic groups, and businesses across the world. In Thailand, a leading company like SCG has embraced the concept and expanded into a collaboration with different sectors under the initiative “The Sea Saver” to sustainably conserve the ocean and develop innovation to safeguard and restore the ecosystem the coast and at sea.

Enhancing Solutions with Innovations and Digital Technology

According to data compiled by the Department of Marine and Coastal Resources, Thailand has generated 27.8 million tons of plastic debris each year, and of which an estimate of 7.36 million tons was mismanaged and escaped into the sea through rivers and canals. Looking into the source of these wastes, over 80% of marine debris stems from land-based sources, namely, household and residential communities, inland landfill sites, port areas, and seaside tourist attractions. SCG has pledged to empower sustainable development for communities, society, and the environment. It has partnered with the Department of Marine and Coastal Resources (DMCR) to develop SCG-DMCR Litter Trap to provide an effective solution to combat the marine waste problems.

SCG-DMCR Litter Trap

The litter trap innovation was improved from its first prototype, “Oil Boom,” developed by the Department of Marine and Coastal Resources (DMCR) in 2018. With a dimension of 1.8 meters wide and 5 meters long, the litter trap can intercept up to the maximum capacity of 700 kilograms per day. The main material for the SCG-DMCR Litter Trap is PE100 pipes produced in excess during trial productions, lending durability and exampling resource maximization based on the Circular Economy.

SCG developed SCG-DMCR Litter Trap to have a 2-way entrance system using natural water current and pressure to help collect trash floating on the water surface and prevent it from leaking by tidal movement. In 2020, SCG has developed SCG-DMCR Litter Trap Generation 2 made of HDPE-Bone, an upgrade polyethylene compound of HDPE, as a substitute for the material used in generation 1. The new litter trap comes with increased buoyancy and waste interception performance along with UV resistance, a lifespan of 25 years, and recyclability in line with the circular economy.

Striving for Marine sustainability

Since 2019 to date, SCG and the Department of Marine and Coastal Resources (DMCR) have installed 24 SCG-DMCR Litter Traps at the river mouths and canals in 13 provinces to prevent waste entering the ocean. The litter traps could productively intercept over 40 tons of garbage in total. SCG is fully committed to developing innovations so solve marine waste problems, lend its expertise, advance in polymer material technology, and know-how in engineering design into innovation development. Furthermore, the company also focuses on forging collaboration and networking both at home and aboard such as Alliance to End Plastic Waste (AEPW) and The Ocean Cleanup, to drive the effort to sustainably and effectively tackle marine waste.
