Summary: To address global climate change, Net-Zero targets have been set up by various governments, organizations, and companies. Manufacturing companies are urged to improve the energy efficiency of their production systems to combat energy waste. However, the concept of energy waste remains unclear in academia and industry. This study conducted interviews with practitioners from different manufacturing factories to uncover the key characteristics of energy waste. Based on the findings, an energy waste analytic framework was developed, identifying thirteen types of energy waste and proposing a step-by-step strategy for reducing it.

Summary: This study evaluates the uncertainty component of high efficiency gamma-ray spectrometry measurements caused by the uncertainty of the decay parameters. By analyzing a large set of random decay schemes constructed using values and uncertainties from data libraries, the distributions and correlations of coincidence-summing correction factors FC, p·FC (p = photon emission intensity) factors are constructed and analyzed.

Summary: Researchers have developed a first-principles computational scheme to calculate Delta H-ROP for polymer systems, achieving a root-mean-square error of 7 kJ/mol on a benchmark set of 42 ROP polymers. This development paves the way for building a high-quality database of Delta H-ROP for predictive machine-learning models and accelerating the design of depolymerizable polymers.

Summary: This study developed a first-principles computational scheme for accurately calculating the enthalpy of ring-opening polymerization (Delta H-ROP). The scheme demonstrated a smaller root-mean-square error compared to conventional approaches when validated on a diverse benchmark set. This development opens up new pathways for building a high-quality database of Delta H-ROP and accelerating the design of depolymerizable polymers.

Summary: This study analyzed the efficiency of waste management services in Spain from 2005 to 2015, finding that cost efficiency is increased by selective collection and certain political and socioeconomic factors. Municipal direct provision was identified as the least efficient management form for this service.

Summary: This paper proposes a blowdown heat recovery system using a steam dryer and compares it with the use of blowdown heat for feed water heating. Simulation results show that using blowdown heat for steam drying results in a significantly larger net power output, and the integration of this heat recovery system is economically feasible.

Summary: This paper analyzes the impact of selected institutional factors on waste management costs in the Czech Republic. The findings suggest that outsourcing and intermunicipal cooperation help reduce costs, while public mode of production, public-private partnerships, increased market concentration, and provision by multinationals increase costs.

Summary: Recently, there has been growing interest in using organic or biodegradable wastes, including lignocellulosic wastes (LWs), as renewable energy sources. Anaerobic digestion (AD) of these wastes can mitigate environmental damage and produce biogas and bioenergy, which is particularly valuable in developing countries. However, there are several challenges to overcome, such as waste floating on top of reactors, high carbon-to-nitrogen ratio (CNR), complex structure of LWs, and poor degradability due to high lignin content. These challenges can be addressed through methods like mixing in reactors, reducing CNR, balancing inoculum-to-substrate ratio (ISR), and pretreatments. This study aims to review the literature on AD of LWs, identify existing challenges, and propose strategies to improve bioenergy production from this waste.

Summary: The UK needs to decarbonize low temperature industrial waste heat to achieve net-zero greenhouse gas emissions. The potential and applications of low temperature industrial waste heat in the UK are not well known, and quantifying the resource can drive the development of green technologies. Research shows that the recoverable potential of low temperature waste heat in the UK industry is significant and offers important opportunities for recovery and utilization.

Summary: A pressurized gasification combined system integrated with geothermal energy is studied for the production of hydrogen-enriched syngas. The system utilizes dewatered sludge from the wastewater treatment process as a feedstock to produce hydrogen, which is then transformed into electricity for community use. The system also incorporates a wind farm and hydrogen storage system to meet fluctuating energy demands. Thermodynamic-based analysis and simulation are conducted to assess the system's performance, and the Greater Toronto area is chosen as the case study location. The overall energy and exergy efficiencies of the waste-to-energy system are calculated as 32.7% and 36.6%, respectively.

Summary: The USDA's FSIS requires foreign countries to demonstrate that their food safety inspection system provides the same level of public health protection as the FSIS inspection system in order to make an equivalence determination. A risk metric is presented to evaluate microbiological testing data, and the margin of equivalence is defined as a multiple of the standard error of the U.S. prevalence estimate. This approach provides high confidence in determining whether a foreign country's product poses no greater risk of foodborne illness.

Summary: To address climate change, governments around the world have set their own carbon neutrality targets based on their own realities. This study conducts a literature review to propose narrow and broad definitions of energy waste and a theoretical framework to comprehensively reduce energy waste. However, there is currently no clear definition of energy waste and lack of consensus on the topic. Most previous studies focus on reducing unnecessary energy consumption through management techniques, while digital technologies can also play a facilitating role. Future research directions include case studies to further understand energy waste and developing a more detailed framework on the topic.

Summary: Currently, industrial companies are becoming increasingly aware that a significant amount of the energy they consume each year is being wasted as waste heat. Despite growing awareness, incentives, and the availability of mature and market-ready waste heat recovery technologies, industrial heat recovery measures are still not being implemented, mainly due to non-technological barriers. These barriers include the lack of reliable data on heat consumption, waste heat recovery potentials, and the types, costs, and benefits of heat recovery practices. The aim of this study is to fill this information gap for the textile sector by providing a knowledge base derived from real industrial data collected through a large-scale survey. These findings can be used by companies to identify and evaluate potential heat recovery opportunities for their processes, and by academics and policymakers to estimate recovery potentials.

Summary: This study investigates the physical and electrical phenomena associated with ph-to-ph faults in different tree species, and proposes a method to identify the stages of ignition. The results show that by analyzing the rate change of the RMS current and zero-crossings, ignition stages can be accurately identified. Additionally, a volatility detector is proposed to detect RMS current volatility during a HIF event, using the concept of relative volatility.
