The authors present a fairly extensive analysis of the state of the cereal crop industry in the Republic of Tajikistan and other regions of East and South-East Asia. Problems of generation of a huge amount of waste in the course of processing of cereals, in particular, rice straw processing by-products, are raised by the authors. The authors propose their original solution to the problems in question. Besides, traditional and original methods of application of rice straw in low-rise construction and production of building materials are presented in the article. The major part of the article covers traditional methods of disposal of rice straw as a raw material used in the production of cellulose, lignin biodegradable plastic, paper, cardboard, wicker products, thermal energy, etc. Another important issue, covered in the article, is the study of the straw/husk burning process, as well as the possibility of generating ash that contains various forms of silica. The fact that the ash content of the straw, according to various sources, varies within the range of16–20 %, and its silica content may be up to 89–91 % make it possible for the authors to state that straw and husk ash can be used as an active mineral additive in the production of effective building materials. It is noteworthy that the problems raised in the article are relevant, and their practical solutions are feasible.
