Sustainable Utilization of Bio-fuel Co-Product in Roadbed Stabilization

Abstract

The sustainable utilization of bio-fuel co-products (BCPs) in construction application promises to support the viability of a growing bio economy and provides green construction practices. Biofuel production creates many different co-products depending on the method of biofuel production and co-products recovery technique and the biomass source. Among various BCPs, the industrial application of the BCP containing lignin has been limited although lignin is one of largest fractions of lignocellulosic biomass. This chapter discusses the utilization of BCP containing lignin in geotechnical engineering practices. Special attention is given to the experimental evaluations and pavement damage analysis to demonstrate the BCP containing lignin is a promising soil stabilization material, which can lead to dramatic breakthroughs for improving the durability, efficiency, economy, environmental impact, and sustainability aspects of civil engineering infrastructure systems. © Springer-Verlag London Limited 2012.
