In the management of urban solid waste (MSRS), we still have not classified solid waste according to the level of sustainability, the ability to decompose for all types of solid waste from different sources
as well as the division of different physical streams of urban municipal solid waste. Plant-derived CTRHCs are collectively collected with other CTRHC to produce com-post, which makes it difficult and complex to process and process. The composition of plant cells includes the following six substances: cellulose, inulin, chitin, xylan, pectin, lignin. The breakdown of cellulose in natural conditions also involves two components, pectin and lignin, which are often combined with cellulose to lignocellulose and pectinocellulose. However, cellulose is one of the key components of plant organisms, which is a very stable high molecular weight polysaccharide compound. Within the limits of the paper, the author only focused on cellulose - cellulose molecular structure, cellulose resolution mechanism
solutions to collect, classify and classify solid waste matter according to the characteristics and properties of waste, as well as techniques and technologies for the treatment of non-persistent organic solid waste with plant origin.Trong quản lý chất thải rắn sinh hoạt (CTRSH) đô thị, chúng ta vẫn chưa phân loại chất thải rắn theo mức độ bền vững, khả năng phân hủy đối với các loại chất thải rắn thực vật có nguồn phát sinh khác nhau
