Special Issue Information

Dear Colleagues,

The growing number of manufactured and consumed products causes not only an increase in the amount of waste generated that requires processing but also in the associated GHG and air pollutant emissions. Moreover, using the produced biomass instead of fossil fuels for energy purposes may help mitigate GHG emissions. Therefore, there is a need to supplement our knowledge on the role of the waste sector as a source of greenhouse gas (GHG) and air pollutant emissions and that of bioenergy in the production of neutral or negative carbon emissions. Further studies assessing the effects of replacing non-renewable energy sources with energy from waste or biomass, as well as other measures, on reducing GHG or air pollutant emissions are also needed. I therefore invite you to submit valuable research or review papers in this area and co-create content for this Special Issue (SI).

This SI covers all aspects related to the assessment and mitigation of GHG and air pollutant emissions in the waste sector, bioenergy and related activities, and possible or observed energy and environmental effects. Topics of interest for publication include, but are not limited to, the following:

  • GHG mitigation;
  • Air pollution prevention and control;
  • GHG and air pollutant emission factors;
  • Waste recovery or disposal and GHG/air pollutant emissions;
  • Air pollution from waste/biomass fires or open burning;
  • Circular waste management systems;
  • Biomass waste as a renewable carbon material;
  • Waste to energy;
  • Biomass power and heating conversion pathways;
  • Energy/bioenergy conversion efficiency;
  • Biofuels and the problems or benefits of their use;
  • Waste incineration or co-combustion with carbon capture and storage (CCS);
  • Bioenergy with CCS;
  • Lifecycle assessment;
  • Carbon footprint in waste sector and bioenergy.

Air pollution remains a critical environmental and public health issue, requiring diverse research perspectives, including those related to energy production and consumption. This study examines the relationship between Poland’s energy mix and air pollution trends by integrating national statistical data on primary energy consumption and renewable energy sources over the past 15 years with air pollution measurements from the last eight years. The air pollution data, obtained from reference-grade monitoring stations, focus on particulate matter (PM). To address discrepancies in temporal resolution between daily PM measurements and annual energy sector reports, a bootstrapping method was applied within a regression framework to assess the overall impact of individual energy components on national air pollution levels. Seasonal decomposition techniques were employed to analyze the temporal dynamics of specific energy sources and their contributions to pollution variability. A key aspect of this research is the role of renewable energy sources in air quality trends. This study also investigates regional variations in pollution levels by analyzing correlations between geographic location, industrialization intensity, and the proportion of green areas across Poland’s administrative regions (Voivodeships). This spatially explicit approach provides deeper insights into the linkages between energy production and pollution distribution at a national scale. Poland presents a unique case due to its distinct energy mix, which differs significantly from the EU average, its persistently high air pollution levels, and recent regulatory changes. These factors create an ideal setting to assess the impact of energy sector transitions on environmental quality. By employing high-resolution spatiotemporal big data analysis, this study leverages measurements from over 100 monitoring stations and applies advanced statistical methodologies to integrate multi-scale energy and pollution datasets. From a PM perspective, the regression analysis showed that High-Methane Gas had a neutral impact on PM concentrations, making it a suitable transition energy source, while renewables exhibited negative regression coefficients and coal-based sources showed positive coefficients. The findings offer new perspectives on the long-term environmental effects of shifts in national energy policies. Full article

In light of growing global supply chain instability and carbon neutrality initiatives, South Korea has highlighted the need for a circular economy to reduce its reliance on natural resources. As a critical strategy for promoting a circular economy, remanufacturing has become essential because of its ability to improve resource efficiency and reduce environmental impacts. The automotive sector, which accounts for 80% of the remanufacturing industry, plays a critical role in these efforts. Turbochargers, primarily made of cast iron, represent approximately 20% of sales in this sector and are significant contributors to greenhouse gas emissions, making them an important target for emission reduction. This study examined the greenhouse gas emissions associated with turbochargers across multiple remanufacturing cycles using the LCA method. The results indicated an approximate decrease of 50%, 48%, and 46%, based on a comparative analysis between brand-new products and those remanufactured one to three times. Comparing brand-new and remanufactured products does not fully capture the key advantage of remanufacturing. This advantage lies in its ability to extend a product’s life cycle by using core parts as primary raw materials and reducing the consumption of new resources. Therefore, it is important to consider the environmental impact of remanufacturing within an expanded process, where brand-new products are included in the entire life cycle. Using this approach, the accumulated annual greenhouse gas reduction effect for multiple remanufacturing indicated decreases of approximately 25%, 32%, and 35% for remanufacturing one, two, or three times, respectively, compared to using only brand-new products. This study shows that multiple remanufacturing reduces greenhouse gas emissions compared to the use of brand-new products. In particular, as remanufacturing is repeated, the product lifespan can be extended from 3 years to up to 12 years with a concomitant decrease in annual greenhouse gas emissions. These findings provide valuable data for modeling and encouraging the greenhouse gas reduction potential driven by remanufacturing across various industrial sectors. Full article
