Title in English: Compost types, feedstocks and composting methods
Abstract / summary in English:
Compost types are characterized by feedstocks, composting processes and compost maturity. Feedstocks for composting differ greatly in carbon and nutrient contents, moisture and salinity. Mixing different feedstocks is necessary to obtain a good compost quality. Not only is the C/N ratio of the starting materials important to consider, but also the C/P and N/P ratios. Different feedstocks also result in different structured starting mixes and different moisture contents, which is important for good aeration during the composting process. A wide range of composting methods has been developed. A broad division can be made between the level of technology used, e.g. with or without forced aeration, and if the system is open or closed to the environment. The degree of maturity is an important characteristic of compost, which is determined by the management and duration of the curing phase.
