“…Compared with developed countries, contents of solid waste in China are more similar to other developing countries. The moisture content of solid waste in China is much more than that in developed countries while the heating value is much lower [35]. China is still not able to recycle some types of solid waste, which can be recycled in the US or Japan [5].…”

China meets increasingly serious solid waste problems and has adopted various policies in response in recent years. Meanwhile, few studies have investigated the performance of solid waste disposal through statistical analysis with empirical data. This study examines provincial resource use policy's influence on the comprehensive utilization rate of industrial solid waste in Chinese cities. Through comparing results for statistical analysis in the year 2009 and 2015 by multiple linear regression analysis, this study analyzes similarities and differences in the drivers for solid waste disposal in the era of the 11th Five-Year Plan and the 12th Five-Year Plan in China. It finds that the adoption of resource use policy positively increases the comprehensive utilization rate of industrial solid waste. Other factors such as industrial SO 2 emission, local environmental regulations, GDP per capita, population density and educational level also affect industrial solid waste disposal. Therefore, China should continue implementing solid waste disposal policies, upgrade current industrial systems, push forward economic and social reform and increase environmental education to enhance the effectiveness of solid waste disposal for long-term sustainable development.

Abstract-In this paper, a review on applications of hydrothermal treatment (HTT) for upgrading waste materials was presented. This work was focused on pilot-scale HTT processes that applied to several kinds of waste for alternative solid biofuel production. The HTT utilizes subcritical water condition that has special properties as an organic solvent. With the temperature around 180-240 °C and the corresponding pressure that keeps the water in the liquid phase, many reactions are induced by the subcritical water such as hydrolysis and dehydration. The waste materials that had been subjected to the HTT processes by pilot-scale reactors such as paper sludge, antibiotic residue, and municipal solid waste were reviewed herein. Moreover, a novel application of HTT on hospital waste treatment has been carried out in a pilot-scale level. Results showed positive effects and consistency with the previous research works. Thus, the HTT showed possibility to be an option for pretreating waste materials prior to final conversion processes.Index Terms-Hydrothermal treatment, high moisture waste, pilot-scale hydrothermal, solid biofuel.

“…The residues usually have high moisture content (around 80%) which leads to various problems during direct combustion process. Hard to ignite, unsteady and unstable combustion, incomplete combustion, and huge amount of gaseous pollutants are due to high moisture content [9]. High chlorine contents in biomass would cause corrosion problems whereas high alkaline metal, such as potassium (K), is responsible for slagging fouling problem in the heat transfer equipment.…”

Agricultural and agroindustrial wastes are increasingly being used for the generation of fuel products. Banana residues has a potential to be used as biomass energy sources in tropical country due to its availability, fast growing characteristic of banana plant, carbon neutrality and the fact that each banana plant bears only one stem of fruit. Thermal conversion of biomass to higher energy density fuels is gaining a growing interest as it is sustainable and has a potential to reduce greenhouse gasses. However, many forms of biomass in the waste stream, including banana residues, have very high moisture content, which makes them both inefficient to store, transport, and process using conventional technology. The hydrothermal treatment (HT) is known for converting high moisture content solid wastes into dried, uniform, pulverized, coallike solid fuel. In the present study, banana leaves was characterized and subjected to HT in a batch process to evaluate the suitability of these biomass sources for solid fuel production. Banana leaves was treated via HT at the temperatures of 180 and 200° C with the holding time of 30 min. The results showed that HT can increase the carbon and energy content of banana leaves, while the ash content decreased with the increased of temperature. The calculated value for theoretical potential power generation from treated banana leaves is 3.8 GW. These results showed that the production of solid fuel from banana leaves by employing hydrothermal treatment can contribute to the development of renewable energy, especially in Indonesia.
