Comparison of the evolution of physicochemical and microbial characteristics of the wastes, those most commonly generated in Algeria during composting

Purpose This paper focuses on monitoring the behavior of five different types of waste and humus during composting to see the impact of the nature of the substrate on the process and the quality of mature compost. Method Green waste, coffee waste, household waste (Fraction of the household waste whi...

Method Green waste, coffee waste, household waste (Fraction of the household waste which having dimensions smaller than 8 mm) and humus were collected separately from different areas of Oran city, western Algeria, composted in windrows of 2 m long, 1 m wide, and 0.5 m high each for 150 days during the winter and spring period (2019-2020).
