“…Organic material is derived from natural sources. Essentially, any residual kitchen waste (vegetable peelings, food, tea bags, and egg shells), agro-waste (food and beverage processing waste, dairy products, animal waste, and crops), grass clippings, dried leaves, and timber can degrade naturally (Hartono et al, 2015;Ng & Yusoff, 2015;Kadir et al, 2016). The process of degradation is performed by microbial (fungi, bacteria, actinomycetes, and protozoa) and invertebrate (insects and earthworm) organisms, which digest and break down the organic matter (Basri et al, 2005;Fauziah & Agamuthu, 2009;Kadir et al, 2016).…”
