Summary: Combined heat and power systems can reduce energy and carbon footprints of wastewater treatment plants, but high capital costs may deter their installation. This study uses annual and hourly data to size a combined heat and power system for a wastewater treatment plant and calculates the savings. The results show discrepancies between the annual and hourly analyses, mainly due to the variability in biogas and natural gas consumption.

Summary: Large shares of variable renewable electricity (VRE) generation increase the demand for flexible power balancing capacities. Thermal energy storage (TES) can be used to increase heat-load flexibility and improve power balancing capacity in district heating (DH) production systems. A study on Swedish DH systems shows that they could reduce power deficits and surpluses by approximately 9% respectively, and heat pumps can contribute to reduced fuel use in DH production.

Summary: This study designed and simulated a polygeneration system that integrates a ground source heat pump and anaerobic digestion units for co-generation of cooling, heating, and biogas. The investigation in a rural village in Chongqing, China showed that the integrated system can save energy and costs compared to separated and current systems. Increasing the operating temperature of the heat pump improved exergy efficiency but decreased overall energy efficiency ratio. Increasing the coefficient of performance of heat pump units enhanced energy and exergy efficiency.

Summary: Granular energy technologies, with smaller unit sizes and costs, have advantages in faster deployment, job creation, and wider distribution of benefits compared to large-scale alternatives. A study analyzed 93 green recovery funding programs in France, Germany, South Korea, and the UK, and found that South Korea's program had the highest technological granularity, focusing on distributed renewables, smart technologies, and low-cost technologies that are quick to implement. The UK, on the other hand, concentrated public funds on a few mega-scale energy projects with high implementation risks, resulting in the least granular portfolio. The study demonstrates the importance of technological granularity in achieving green recovery goals.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
