Conditions for energy generation as an alternative approach to compost utilization

Abstract

Very strict limits constrain the current possibilities for compost utilization in agriculture and for land reclamation, thus creating a need for other compost utilization practices. A favourable alternative can be compost utilization as a renewable heat source - alternative fuel. The changes of the basic physical-chemical parameters during the composting process are evaluated. During the composting process, energy losses of 920 kJ/kg occur, caused by carbohydrate decomposition (loss of 12.64% TOC). The net calorific value for mature compost was 11.169 kJ/kg dry matter. The grain size of compost below 0.045 mm has the highest ash content. The energetic utilization of compost depended on moisture, which can be influenced by paper addition or by prolonging the time of maturation to six months.

Unburned carbon from coal combustion ash: An overview

“…[8,26,45] -effect of coal mineral matter [8,16,26,46] -coal blending [32,39,44,[47][48][49] -co-combustion of coal with alternative fuels [50][51][52][53][54].…”

Biodegradation of organic compounds during co-composting of olive oil mill waste and municipal solid waste with added rock phosphate

“…[26] It also homogenizes the composting material while re-establishing porosity and increasing the active surface area. The windrows of compost were aerated by mechanical turning for five months, (once a week for the first month then once a fortnight for the next four months).…”

Behavior of Cd during Coal Combustion: An Overview

“…In addition to different moisture levels in individual coals, even more significant effect can be expected if coal is co-combusted with wastes, from which some typically contain higher moisture levels, such as sewage sludge, agricultural or forest residues, etc. [81,82].…”
