Does the classification of kitchen waste rely on economic means?

The initial intention of kitchen waste classification is to use it, but most of it can't be used in practice, and it faces problems such as the land area accepted by compost and the treatment cost.

Land area accepted for composting: In Germany, for example, the requirement for household composting is at least 50 square meters of garden area per capita, but urban residents in China do not have such conditions.

Treatment cost: Take the closed kitchen waste factory in Singapore as an example, the profitability is obviously lower than expected, and the cost of anaerobic digestion or composting is much higher than that of incineration, so it cannot compete with incineration under the same price system.

The classification of kitchen waste in developed countries and regions mainly depends on economic means, not administrative means, and no charge or less charge is adopted for the separated kitchen waste.

In Germany, for example, the average domestic waste payment in Germany is 12-20 euros/month, accounting for 0.5%-0.8% of household expenditure, which is basically close to the water fee expenditure. The kitchen waste in Munich, Germany is free, and other garbage is charged according to the size and frequency of the trash can. Berlin, Germany, charges less for kitchen waste to promote classification, and charges differently. Other garbage 120L trash cans charge 67.9 euros per quarter and 271.6 euros per year. The 120L trash can for kitchen waste charges 27.09 euros per quarter and 108.36 euros per year. About 1/3 of the charge for other garbage.
