Compost oversize fraction composition

key words: compost, woodchip, oversize fraction, waste to energy

Summary:

This article is focused on the problematics of compost oversize fraction composition. The main aim was to determine the ratio of woodchips in oversize fraction of sieved compost for its further energy utilization. Ten compost oversize fraction samples of the weight of 100 kg (each sample) were collected at Central Compost Plant Brno in the period from 10.11.2014 to 20.3.2015. The samples were manually sorted to four fractions: 1) soil, 2) wood, 3) minerals, 4) other parts. The fraction analysis revealed that more than 70% of oversize compost fraction consist of soil while the ratio of woodchips is less than 14% only. The ratio of minerals and other parts is less than 10% or 5% respectively.
