Materials and energy recovery at six European MBT plants

A. C. (Thanos) Bourtsalas et al.

Summary: Mechanical Biological Treatment (MBT) is a waste management method that combines sorting of recyclable materials with composting/digestion of green/food wastes and, in some cases, production of fuel materials. The authors visited six MBT facilities in Europe and found that the compost product of most facilities did not meet agricultural standards. MBT plants without fuel material recovery had lower landfill diversion rates and costs. Therefore, an efficient sorting and recyclables recovery line, sufficient gate fee, and fuel material recovery process are necessary for a successful MBT plant to increase revenue and reduce greenhouse gas emissions.

Environmental Life Cycle Assessment of Hydrothermal Carbonization of Sewage Sludge and Its Products Valorization Pathways

G. Mannarino et al.

Summary: This study compares the environmental performances of a Water Resources Recovery Facility (WRRF) and a hydrothermal carbonization (HTC) plant for sewage sludge treatment. Results show that the HTC-based scenarios exhibit improved performances, with a reduction of 98% in the Climate Change indicator. Anaerobic digestion further reduces impacts, while phosphorus recovery negatively affects most indicators.

Hydrothermal Carbonization of the Wet Fraction from Mixed Municipal Solid Waste: A Fuel and Structural Analysis of Hydrochars

Maciej Sliz et al.

Summary: The study shows that hydrothermal carbonization has a positive effect on the properties of under-sieve fraction of municipal mixed waste, improving its fuel properties. By altering process parameters, the fuel properties of hydrochars can be enhanced, making them more suitable for energy production.

Hydrochar and pyrochar for sorption of pollutants in wastewater and exhaust gas: A critical review

Ziyun Liu et al.

Summary: Biochar, a sustainable adsorbent derived from abundant bio-wastes, can be used for the sorption of pollutants in wastewater and exhaust gases. This study compares and discusses the adsorption performance of pyrochar and hydrochar, including preparation procedures, sorption mechanisms, and physiochemical properties. Challenges and perspectives for designing efficient and environmentally friendly biochar-based adsorbents are also addressed.

Hydrothermal carbonization of olive pomace and determining the environmental impacts of post-process products

A. Suna Erses Yay et al.

Summary: This study aimed to explore the potential of producing fuels with high carbon content from waste biomass using hydrothermal carbonization methods. The results showed that energy values increased significantly with higher temperatures, longer residence times, and biomass-to-water ratios, while hydrochar yield decreased with increasing temperature and residence time.

Life cycle assessment on the treatment of organic waste streams by anaerobic digestion, hydrothermal carbonization and incineration

Felix Mayer et al.

Summary: By analyzing the environmental and economic performance of custom treatment paths for organic waste streams in Germany, it was found that anaerobic digestion followed by spreading of digestate is beneficial for food waste and OFMSW, while direct incineration is a preferable option for waste wood. The implementation of an HTC process for OFMSW and food waste is also viable, but must be optimized for an environmentally friendly heat source. In some cases, cascading anaerobic digestion with the HTC-process can be a suitable alternative.

BIOGEOCHEMICAL AND MECHANICAL CHARACTERIZATION OF THE LANDFILL FRACTION GENERATED BY MECHANICAL WASTE SORTING

Emelie Andersson et al.

Summary: Resource recovery from mixed waste streams generates new mixed waste streams which may not fit well to existing waste management options. One type of such waste is the under sieve fraction generated when recovering metals and fuel. Despite high organic carbon content and some trace elements, this material can be safely landfilled with special care given to dewatering the interior to avoid water pressure buildup.

Comparative life cycle energy and greenhouse gas footprints of dry and wet torrefaction processes of various biomass feedstocks

Maryam Akbari et al.

Summary: This study compares the life cycle energy consumption and greenhouse gas emissions of electricity generation from bio-coals produced from various biomass feedstocks via dry torrefaction and wet torrefaction processes. Results show that most pathways are competitive with coal-based electricity in terms of GHG emissions, with pine woodchips biochar-based electricity generation being the best option in terms of emissions reduction and net energy ratios. Sensitivity analysis of various factors was conducted, and the developed information can be used for investment decisions and policy formulation globally.
