Construction Biotechnological Plastics

Abstract

Plastics that are used in the construction industry produce hazardous nonbiodegradable wastes after demolition of the buildings or temporal constructions. Recent investigations on bioplastic reveal a new and sustainable construction bioplastics made from the renewable organic sources that can be left in soil or composted after demolition because of their biodegradability. Bioplastics also have the potential to lead to the rise of new building materials with low embodied energy thus contributing to energy building efficiency. Cheap raw materials, continuous, and nonaseptic cultivation of mixed bacterial culture, and production of crude composite bioplastic as construction material with low embodied energy has to be used to enhance bioplastic cost-efficiency. Bioplastic can be produced as by-product of biorefinery using acidogenic fermentation or pyrolysis of lignocellulosic biomass, as well as by-product of biotreatment of solid or liquid municipal wastes.
