Waste-to-energy supply chains are important potential contributors to minimising the environmental impacts of municipal solid waste by reducing the amounts of waste sent to landfill, as well as the fossil fuel consumption and environmental footprints. Accounting for the spatial and transport properties of the waste-to-energy supply chains is crucial for understanding the problem and improving the supply chain designs. The most significant challenge is the distributed nature of the waste generation and the household energy demands. The current work proposes concepts and a procedure for targeting the size of the municipal solid waste collection zone as the first step in the waste-to-energy supply chains synthesis. The formulated concepts and the provided case study reveal trends of reducing the net greenhouse gas savings and energy recovery by increasing the collection zone size. Population density has a positive correlation with the greenhouse gas saving and energy recovery performance. For smaller zone size the energy recovery from waste approaches and in some cases may surpass the energy spent on waste transportation. The energy recovery and greenhouse gas savings remain significant even for collection zones as large as 200 km2. The obtained trends are discussed and key directions for future work are proposed.

Resource recovery from wastewater is a key function of bioelectrochemical systems. NEW resources to recover include Nutrient, Energy, and Water. Identifying proper application niches can guide BES research and development. More efforts should be invested to the application of recovered resources. A mindset for energy performance and system scaling is critically important.

对沁水盆地南部柿庄北区块进行了深煤层注入地质和工程评价,认为柿庄北区块适合进行深煤层注入CO2开采煤层气技术的应用;通过SX-001井的微型先导性试验,对SX-001井的注入前后产气量与产水量、气体成分变化和井底压力变化规律进行了总结。通过现场试验,注入CO2后SX-001井的产气量是注入前的2.45倍;在小于煤岩破裂压力的条件下,每天注入20 t的CO2能够实现顺利注入,并且压力上升速度较慢;注入CO2后,煤岩发生膨胀,局部煤层的渗透率降低,排采一段时间后恢复;在目的煤层中注入的CO2的影响范围内,烃类气体总的置换效率达到14.18 cm3/g。该试验成果证明柿庄北区块通过注入CO2开采煤层气实现了CO2的埋藏,提高了煤层气井的采收率。

In this paper the reliability and performance of a vapour compression refrigeration system with ZnO nanoparticles in the working fluid was investigated experimentally. Nanorefrigerant was synthesized on the basis of the concept of the nanofluids, which was prepared by mixing ZnO nanoparticles with R152a refrigerant. The conventional refrigerant R134a has a global warming potential (GWP) of 1300 whereas R152a has a significant reduced value of GWP of 140 only. An experimental test rig is designed and fabricated indigenously in the laboratory to carry out the investigations. ZnO nanoparticles with refrigerant mixture were used in HFC R152a refrigeration system. The system performance with nanoparticles was then investigated. The concentration of nano ZnO ranges in the order of 0.1% v, 0.3% v and 0.5%v with particle size of 50 nm and 150 g of R152a was charged and tests were conducted. The compressor suction pressure, discharge pressure and evaporator temperature were measured. The results indicated that ZnO nanorefrigerant works normally and safely in the system. The ZnO nanoparticle concentration is an important factor considered for heat transfer enhancement in the refrigeration system. The performance of the system was significantly improved with 21% less energy consumption when 0.5%v ZnO-R152a refrigerant. Both the suction pressure and discharge pressure were lowered by 10.5% when nanorefrigerant was used. The evaporator temperature was reduced by 6% with the use of nanorefrigerant. Hence ZnO nanoparticles could be used in refrigeration system to considerably reduce energy consumption. The usage of R152a with zero ozone depleting potential (ODP) and very less GWP and thus provides a green and clean environment. The complete experimental results and their analysis are reported in the main paper.
