“…Another potential feedstock for expansion of biodiesel production is jatropha, which is available in Sichuan, Guizhou and Yunnan provinces. Jatropha has advantages in that it can be grown on marginal lands and demonstration projects with capacities of greater than 10,000 tons per year are under construction in Guizhou and Yunnan (Wu et al, 2010). However, jatropha-based biodiesel production faces problems in reaching mass production scale, mechanized collection of crops and effective utilization of residues.…”

“…Due to China's reliance on grain-based fuel ethanol and its competition with food production on limited arable land, recent policies have limited the expansion of existing bioethanol production and halted new project approvals. In particular, new grain-based fuel ethanol plant project approvals were stopped indefinitely in 2006 (Wu et al, 2010). In addition, the government is also limiting corn starch based bioethanol projects with processing capacity of less than 300,000 tons per year and has eliminated projects with annual capacity of less than 100,000 tons per year (Agra Europe, 2011).…”

“…The plant design was developed with help from West Virginia University and has a production capacity of one million tons per year with a daily output of 25,000 barrels of oil. On an annual basis, 3.45 Mt of raw coal is used to produce 1.1 Mt of fuel and oil products, including 715,000 tons of diesel, 250,000 tons of naphtha and 102,000 tons of LPG (Wu, 2010). Shenhua is planning on expanding its CTL capacity target to 3 million tons per year by 2015 with another CTL plant in Ningxia awaiting NDRC approval.…”

“…For sweet sorghum, China currently has over 125 resources registered and a 5000 ton per year demonstration project was established with support from the National High Tech program (Wu et al, 2010). Lignocelluloses, which include crop residue, grass, sawdust, wood chips, solid animal waste and industrial waste are being explored in research and development projects at several major universities including Tsinghua University.…”

“…Lignocelluloses, which include crop residue, grass, sawdust, wood chips, solid animal waste and industrial waste are being explored in research and development projects at several major universities including Tsinghua University. However, both feedstock face challenges in the storage and pretreatment of feedstock and low conversion rate and high energy consumption of production processes, with efficiencies ranging from 12% to 14% for fresh cassava and 15% to 25% for dilute acid and enzyme hydrolysis (Wu et al, 2010).…”

Crop residue resources are known to provide important lignocellulosic biomass that can be used as feedstock. This study evaluates spatiotemporal variation in residue quantities of field crops across seven provinces in East China (EC) and six provinces in Central-South China (CSC). MATLAB and Map GIS were used to analyze the data, which was collected from yearbooks and the published literature. The results show that cereals such as wheat, maize, and rice comprised the largest crop residue feedstock resource across both regions over the period between 2017 and 2019. Thus, annual total residue amounts were 206 Mt in EC and 243 Mt in CSC. This means that, when expressed as total standard coal equivalent (SCE), the amounts were estimated as 107 Mt in EC and 127 Mt in CSC. Compared with previous research, CSC exhibited the highest crop residue production and potential for biofuels, whereas EC exhibited one of the lowest potentials for biofuels among the six regions of China. This study is the first to evaluate the spatial distribution of annual field residue quantity based on counties in the two regions.The key factors influencing the availability of biofuel feedstock included storage capacity (X 3 ), irrigation acreage (X 4 ), and fertilizer input (X 5 ) while the degree of mechanization also played a role in the CSC region. In contrast, the field residue quantity across the EC region was significantly (P < 0.01) influenced by these three factors.

Summary China, one of the countries in the world abundant in agricultural wastes, has a great potential for rural biogas production. As a strategy for building a new socialist countryside and sustainable agriculture in rural China, the development of biogas is an important means to convert agricultural wastes to clean and safe energy, thereby reducing the need for fossil fuel and alleviating environmental pollution. This study presents an assessment of the biogas production potential, its current development state, and perspectives of agricultural wastes in rural China. Estimated data show that annual biogas potential from agricultural wastes is approximately (3350.58 ± 669.28) × 108 m3 (equal to 239.22 ± 47.78 million tons of equivalent standard coal); such potential has been underutilized in the past. By analyzing and summarizing the direction for future development and various benefits of rural biogas in China, we present burning questions and countermeasures for biogas development and recommend that the future development of rural biogas in China should focus on both household‐scale and large‐scale development, giving priority to the establishment of large‐scale biogas engineering and biogas plants, improvement of biogas comprehensive utilization level, and construction of a reticular model of systemized green agricultural engineering linked with biogas to solve completely the problem of agricultural waste accumulation and improve the living conditions in rural China.
