Biological conversion for agricultural waste from corn, rice, wheat, and sugar is considered one of the sustainable agricultural waste management technologies and an eco-friendly strategy with economic feasibility. Through the biological conversion of cellulose, hemicellulose, and lignin, environmentally friendly products can be created and further developed into various applications, such as xylitol, ethanol, and phenylacetylcarbinol (PAC).

Abstract: 
Corn, rice, wheat, and sugar are major sources of food calories consumption thus the massive agricultural waste (AW) is generated through agricultural and agro-industrial processing of these raw materials. Biological conversion is one of the most sustainable AW management technologies. The abundant supply and special structural composition of cellulose, hemicellulose, and lignin could provide great potential for waste biological conversion. Conversion of hemicellulose to xylitol, cellulose to ethanol, and utilization of remnant whole cells biomass to synthesize phenylacetylcarbinol (PAC) are strategies that are both eco-friendly and economically feasible. This co-production strategy includes essential steps: saccharification, detoxification, cultivation, and biotransformation. In this review, the implemented technologies on each unit step are described, the effectiveness, economic feasibility, technical procedures, and environmental impact are summarized, compared, and evaluated from an industrial scale viewpoint.

Keywords: Agricultural waste; Co-production; Ethanol; Xylitol; Phenylacetylcarbinol
