1. Environmental characteristics of plastic trash cans
Recyclability
Plastic trash cans are usually made of recyclable plastic materials. For example, common plastics such as polyethylene (PE) and polypropylene (PP) can be remade into other plastic products after recycling, reducing the demand for original resources.
Durability
They have good durability and can withstand long-term use and various environmental conditions. This means that they do not need to be replaced frequently, thus reducing the generation of waste.
Lightweight
Compared with trash cans made of other materials, plastic trash cans are relatively light, easy to carry and transport, and reduce energy consumption.
Cost-effectiveness
The production cost of plastic trash cans is relatively low, and it can meet large-scale garbage collection needs in a relatively economical way.
2. Environmental requirements of plastic trash cans
Material selection
Environmentally friendly plastic materials should be given priority, and plastics containing harmful substances should be avoided. For example, plastic additives that are difficult to degrade or harmful to the environment should not be used.
Production process
The production process should follow environmental protection standards to reduce energy consumption and pollutant emissions. For example, energy-saving production equipment and clean production processes should be used.
Degradability
Some new plastic trash cans are degradable and can decompose naturally under certain conditions, reducing the long-term impact on the environment.
Recycling logo
Trash cans should have clear recycling logos to facilitate classification, recycling and reuse.
Quality standards
Must meet relevant quality and environmental standards to ensure that they will not cause additional harm to the environment during use. For example, no harmful substances will be released into the environment due to material problems.
For example, some cities are promoting the use of plastic trash cans with QR codes or chips to facilitate tracking and management of garbage classification and recycling, improving environmental protection efficiency. For another example, some communities use plastic trash cans with biodegradable coatings to reduce odor and bacterial growth, while also reducing potential harm to the environment.
