Efficiency of Using Waste after Flax and Hemp Processing

Insufficiency of resources in South Ukraine, economic problems connected with involving a great volume of primary raw materials in economic turnover and obtaining a lot of waste required the development of resource consumption structure, introduction of low waste and wasteless technologies, creation of perfect system of waste utilization. Technological developments carried out at the scientific laboratories of the Kherson State Technical University showed that at certain minimum expenditures there exists the possibility of obtaining real efficiency in processing flax and hemp plants waste in Ukraine.

The economic effect can be obtained at the expense of introduction into production short fibres which cottonizing allows to expand the assortment of fabric and to economize primary raw resources: realization of waste formed in the pharmaceutical industry where they are used for the production of oily substances which provide healing wounds and activated carbon used for clearing organism; using shive as waste substances containing valuable organic substances in pulp and paper industry for the production of paper and board, in wood-chemical industry for the production of wood-fibre and wood-mineral compositions and shiveboards as substitutors for expensive wood. The most considerable economic effect is connected with the application of shive for the development and creation of the whole complex of new building materials and compositions. Their economic importance increases because their production doesn’t require great preparatory and power expenditure. The expention of application of wood-cement compositions as fireboard, sawdust concrete, lignowood concrete allows to satisfy the requirements of large-scale and private building. Taking into account the lack of power resources in Ukraine one can consider perspective and economically benefit the use flax and hemp waste in the form of shive blocks. Maximum efficiency can be obtained by using secondary raw rich in shive in food industry. The results of effective application of flax and hemp waste one can consider the production profitability, saturation of market with new goods of flax and hemp processing and the reduction of negative influence of waste on environment.
