Potential for Bioenergy Production from Sugarcane in China

Abstract

There has been rapid economic development in China in recent decades, and demand for energy has consequently been increasing rapidly. Development and utilisation of clean and renewable energy has been promoted by the Chinese government to help sustain long-term and stable development. Sugarcane is being increasingly used in several countries as feedstock for renewable energy products, and is a major and expanding crop in southern China. In this paper, we discuss the potential of sugarcane as a feedstock for bioenergy production in China. It includes a review of (1) the existing sugarcane industry in China and key bio-physical factors affecting the extent to which sugarcane-based industries could supply feedstock for renewable energy production in China, (2) the economic and policy factors which are likely to affect production of bioenergy from sugarcane in China, and (3) recommendations on actions and policies that may assist with appropriate development of bioenergy production from sugarcane in China. Existing and expected future economic conditions are unlikely to favour production of biofuel from the sugar component in cane. However, the fibre component of cane remains an under-utilised resource component. A conclusion is made that sugarcane fibre has potential to contribute towards renewable electricity production in China. However, at present, favourable incentives do not exist to encourage this production. It is suggested that policies to facilitate cost-effective production of renewable electricity by sugar mills, consistent with national objectives regarding production of renewable energy, be considered by governments. Priorities for future research are in improving biomass yields per unit area of land and technologies for low-cost conversion of lignocellulosic biomass into biofuel.
