Humans can control the temperatures during composting by mixing or turning the organic materials (Figure 1â2). Composting is a biologically mediated decomposition process, in which microorganisms convert organic waste into a stable and nutrient rich humus-like material. As the active composting phase subsides, temperatures gradually decline to around 100ËF. Temperature profiles of all mixtures during composting were measured at every composting stages at various depth in order to determine the compostability level of substrates.

Changes in the composition of solid waste, associated with the level of economic development, have been well-documented in waste management literature. In the active composting stage, microorganisms consume oxygen (O 2) while feeding on organic matter in manure and produce heat, carbon dioxide (CO 2) and water vapour. materials rapidly. No. In the process of composting, microorganisms break down organic matter and produce carbon dioxide, water, heat, and humus, ... when only the most resistant compounds remain in the last stages of the formation of humus. Some of the energy is used by the microorganisms for reproduction and growth; the rest is given off as heat. The curing stage of compost usually lasts 3 to 4 weeks. On the whole, the role of composting stages and the rebounding of ARGs during each stage was still a question.

Compost has undergone: (1) an initial, rapid stage of decomposition; (2) a stage of stabilization; and (3) an incomplete process of humiï¬cation. Introduction Landfill and incineration have until now been the most widely used means of solid Compost bacteria combine carbon with oxygen to produce carbon dioxide and energy. In a compost pile destined to go out in a blaze of glory, the demise of the mesophiles eventually sets the stage for thermophilic composting.

Composting is the decomposition of organic materials by microorganisms under controlled, aerobic conditions to a relatively stable humus-like product suitable for growing plants, which poses no hazard to human health or the environment1. Except when the temperature drops, actinomycetes and fungi are confined to 5 to 15 cm outer surface layer. The process involves decomposition of organic material into a humus-like material, known as compost, which is a good fertilizer for plants. Compost temparature steadily increased until the 10th day of composting and maximum temperatures were recorded at the second turning stage of composting. ��PJII��&..��`a p��H��x� j��Rq �-QR1�A
