1. Separate recycling: separate kitchen waste from other wastes. This can reduce the treatment cost, because kitchen waste can be used to produce organic fertilizer, while other waste needs to be buried or burned, which is more expensive. At the same time, classified recycling can also reduce the total amount of garbage and reduce the treatment cost.
2. Kitchen waste treatment equipment: Use reliable kitchen waste treatment equipment, such as composting equipment and biogas digesters. The treatment cost can be reduced, and the treated organic fertilizer or biogas can be used for agricultural production or energy production to increase income.
3. Reduce kitchen waste: Reducing the amount of waste can reduce the processing cost. This can be achieved by reducing food waste in catering industry and reducing food waste in families. Buying less packaged products and using environmentally friendly tableware can reduce the amount of kitchen waste.
4. Policy and regulation support: The government can encourage and support the classified recovery and treatment of kitchen waste by formulating relevant policies and regulations, such as subsidies for kitchen waste treatment equipment and rewards for classified recovery, so that more people can participate in the classified recovery of waste and reduce the treatment cost.
