Special Issue Information

Dear Colleagues,

The growing world population and the associated increase in consumption of high amounts of resources mean it is necessary to use our resources at an optimum. Reducing waste, ensuring high-quality recycling, and using residual waste for efficient and clean energy generation all together can contribute to resource efficiency. Using biomass, such as municipal wastes, agricultural and forestry residues/wastes, or energy crops, as energy carriers in a diverse range of conversion technologies allows bioenergy to be used in all energy-related sectors: as a fuel in transport (for gasoline, diesel, gas, and electric vehicles), for the production of heating in households, in heating processes in industry, and for electricity generation, where electricity and heat production can be coupled.

With increasing energy demands worldwide, big central solutions as also decentral and local solutions to treat residues/wastes and produce energy need to be developed in a cost efficient and ecological way. 

This Special Issue aims to present and disseminate the most recent advances related to the theory, design, modelling, application, and production of all types of bioenergy.

Topics of interest for publication include, but are not limited to:

- Green hydrogen production;
- Waste to energy (big and small scale);
- Bioenergy;
- Advancements in the RDF technology and its utilization;
- New developments in the energetic treatment of agricultural wastes.

Building zero-waste cities is an important initiative. It helps China to meet the challenges of climate change, build an ecological civilization, and build a beautiful and high-quality China. Through the recycling and safe disposal of waste, the ultimate goal of the construction of zero-waste cities is to minimize the amount of solid waste. Municipal Solid Waste Resource Symbiosis Network (MSWRSN) is the best way to achieve zero-waste cities. However, this system is vulnerable to many factors. These factors will restrict the construction and development of zero-waste cities. This study proposes a vulnerability measurement method of MSWRSN based on energy exchange. Panjin, a city in Liaoning Province, is used as an example to simulate it. The vulnerability measurement method of MSWRSN is composed of three parts. First, the study adopts a directional weighting approach to design the topologic structure of MSWRSN. Second, Dijkstra’s algorithm is used to analyze two topological parameters, node mesonumber and edge mesonumber. It also focuses on single-node failure mode and edge failure mode. Finally, the study uses a functional measure function to calculate the vulnerability of each node and each edge in symbiotic networks. The results of the study show that (1) MSWRSN in Panjin has not yet formed a nested pattern. The symbiotic patterns of different industrial chains are also different. (2) Node failure has a greater impact on MSWRSN. (3) There are differences in the vulnerability of the industry chain in the network. Based on the findings of the study, this study advises managing the vulnerability of MSWRSN from the following aspects. It includes increasing the diversity of symbiotic units, promoting the development of symbiotic networks to nested types, and strengthening risk monitoring and management of core enterprises.

Finding sustainable solutions to the increasing waste generation in Ghana has received a lot of attention in recent years. Through several waste-to-energy processes, the energy potential of municipal solid waste has recently witnessed significant technological advancements. The Renewable Energy Master Plan has projected the production of about 122 MWp from waste-to-energy installations by 2030 in Ghana. To help policymakers and engineers achieve national goals, this paper reviews the waste generation in Ghana estimated from 2010 to 2030 and the status of various bioenergy technologies in Ghana. This paper further estimates the energy recovery potential of municipal solid waste in Ghana under incineration, anaerobic digestion, and landfill gas recovery technologies. The review establishes that, by 2030, municipal solid waste generation will increase by 123% of the 2023 quantities and may produce 1484.25 MW of installed electricity capacity and 13,002.03 GWh per year, which would amount to nearly 59% of Ghana’s 2030 renewable energy target. Additionally, it was determined that anaerobic digestion, incineration, and landfill gas recovery technologies, when properly developed, will add 105.33 MW, 301.4 MW, and 377.31 MW of installed electrical capacity, respectively, to Ghana’s energy mix in 2028.
