-turning waste into treasure

Turning waste into treasure is to use what you have used, will or have abandoned, and use some clever methods to serve yourself again and for your own use. Doing so can reduce garbage and expenses.

This exhibition intuitively introduces the sorting and recycling process of waste such as milk boxes, used laptops and waste plastic bottles through graphic exhibition boards and physical models. The graphic part mainly introduces the process of garbage recycling, and the physical model introduces the process of garbage classification recycling from three stages: waste-recycled raw materials-recycled products.

Milk box packaging is separated into pulp, plastic and aluminum powder through recycling, pulp crushing and other technological processes. Pulp can be used to make recycled paper products, plastic particles can be used to make fibers, spin yarns and further make clothes, while aluminum powder can be used as precious metal to make aircraft cannons or daily necessities. For every recycled 1 ton milk carton, 5 10 kg of paper can be made, 28 kg of plastic 120 kg can be recycled, and 28 kg of aluminum powder can be extracted.

Scrap notebook computers decompose and recycle usable computer components, plastics, and metals such as copper, iron and aluminum through the processes of component disassembly, crushing and sorting. A 2.7kg Dell laptop can decompose 0.488kg plastic, 0.244kg aluminum and 0.015kg iron.

Waste plastic bottles are classified, recycled, unpacked, crushed and other technological processes to generate recycled polyester particles, and then recycled environmental protection fabrics are made by drawing and weaving. On average, every recycled 1 100 million plastic bottles is equivalent to saving 20.1500 million liters of water, reducing emissions by 5.05 million kilograms of carbon dioxide and saving oil1290,000 kilograms.
