摘要

Currently,in Russia,much attention is paid to the recycling and recycling of industrial and household waste.A huge amount of waste is accumulated and not processed in various industries.The bulk of food production waste (beer pellet,alcohol bard,husk) either simply merges,due to the inability of the enterprise to process it,or is used as fuel (husk).In the wood processing industry,there is also no proper processing of the waste (chips,shavings,sawdust).This also includes waste polymer materials,the amount of which increases every year.The relevance of the use of food waste,wood processing,polymer industries in building materials and products is associated primarily with the problems of preserving the environment (they are not subject to decay,corrosion) but also with the problem of resource conservation.At present,the use of polymer waste in the construction materials industry is widespread,and quite an acute problem is the disposal of waste from food and wood processing industries.A particularly promising direction of recycling is the production of high-filled plastics which can be used as construction composite materials.The paper discusses the technology of producing wood-polymer composites by extrusion.It is proposed to.use wheat bran,pre-treated with chemical reagents,in the composite in'addition to traditional components (plastics and sawdust) in the proposed technology.
