Gyongyong Kim, from Servicebio, presented his report of How to Choose Better Recycled Plastics

Gyongyong Kim of Servicebio gives a speech on "How to Choose Better Recycled Plastics," discussing factors to consider in selecting recycled plastics, motives and strategies for sustainable development, as well as the current global plastic demand and waste management situation.

Achieving sustainability: Emphasizing the importance of addressing climate change by reducing greenhouse gas emissions and using renewable energy. International agreements such as the Kyoto Protocol, Paris Agreement, and EU Green Deal have been pushing for sustainable development and a plastic circular economy since the 1992 United Nations Framework Convention on Climate Change.

Global plastic waste situation: Facing significant challenges in plastic waste management globally, with a large amount of plastic waste being landfilled or incinerated while recycling rates remain low. Countries like the EU, US, China, and South Korea exhibit notable differences in plastic waste management, with the US having an 86% landfill rate and South Korea a 73% incineration rate.

Factors to consider in plastic selection: Various factors like economics, quality, safety, supply chain reliability, greenhouse gas emissions, and regulatory compliance must be taken into account when choosing recycled plastics, with the importance of each factor adjusting at different stages.

Recycled plastic technologies: Different plastic recycling technologies have varying impacts on greenhouse gas emissions. Mechanical recycling is suitable for food and beverage plastics, producing food-grade PET, while chemical recycling is suitable for cosmetic and daily plastics, producing non-food-grade PE and PP as well as virgin PET and PE. Thermal cracking technology can convert plastic waste into non-fossil-based naphtha for chemical production. Sevier's carbon-neutral technology offers significant advantages in reducing emissions compared to virgin plastics, with up to 19%-65% less carbon emissions and 30%-100% less virgin plastic usage, 30% renewable solar energy, 15% water savings, and 20% heat recovery through rainwater collection systems.
