The main body of marine plastic garbage is polystyrene blocks (foam plastic) and plastic beads (plastic production raw materials), followed by plastic bags and food containers.
1. Difficult and effective governance methods:
The development of environmentally friendly materials that can replace plastics in terms of performance and price will fundamentally change people's plastic consumption behavior.
Improve the design of landfills and sewers, carry out large-scale construction, and start to combat the erosion of landfills by floods in the next few decades.
Develop controllable or semi-controllable nanomachines that can selectively destroy plastics in water.
2. Difficult and effective governance methods:
Intensify efforts to recycle, landfill, incinerate or special biological treatment of plastic products, and try to avoid plastic waste from flowing into the ocean.
Improve the performance of biodegradable plastics, and find ways to reduce the methane released during degradation.
The carbon dioxide and toxic and harmful substances emitted during the incineration of plastic waste are more effectively recycled and harmless.
Develop genetically modified organisms that can completely decompose plastics in river water and sea water instead of turning them into nanoplastics and sending them into the food chain.
Through legislation, education, and economic measures, people are encouraged to use food containers, cloth shopping bags, net bags, etc. made of wood, glass, ceramics, and metals.
3. Governance methods with low difficulty and low effect:
Floating garbage collection barrier. The Clean Ocean Organization intends to set up floating obstacles in the Great Pacific Garbage Belt, relying on waves to passively collect plastic garbage floating on the sea, and to tow it back to shore for disposal on a regular basis. According to a new study, 200 600-meter-long floating barriers can collect 44,900 tons of floating plastic garbage for 130 years of continuous operation, accounting for about 5% of the estimated floating garbage volume in the middle of this century. Active garbage collection robot. Work efficiency is higher than passive recycling, but the price is much higher.
