6. After termination of the fermentation, the maturated compost should satisfy the
following requirements:
(a) The compost is brown or grey brown, loose, and scentless, and does not
contain mechanical admixtures;
(b) The moisture content is blow 30%;
(c) The carbon–nitrogen ratio (C/N) is smaller than 20:1; and
(d) The oxygen consumption rate is basically stabilized.
4.3.7.3 Aftertreatment
1. The fully decomposed and stable compost products should be crushed, screened,
dried, and granulated.
2. Compost products, as a kind of organic fertilizers, should follow regulations in
standard NY 525; As a kind of microbial organic fertilizers, it needs to accord

plants. After being collected, the leachate can supplement for the primary
fermentation of the raw materials, or discharged after being treated with
sewage treatment facilities. It is prohibited to discharge the leachate directly.
4.3.8.3 Deodorization facilities and medicament should be used or mixed animalcule bacteria of favorable deodorization effect should be inoculated to purify
and eliminate the odor gases such as hydrogen sulfide, sulfur dioxide, and
ammonia.
4.3.8.4 The setting of fire-fighting equipment should meet the fire-fighting requirements and accord with relevant regulations in standards GB 50016 and GB
