Special Issue on
Waste Valorisation for Sustainable Production, Process and Products 

Urban waste management has become a great challenge all over the world. The treatment of waste (municipal solid waste, food waste, wastewater and sewage sludge, etc.) has attracted more and more attentions recently, because the wastes can lead to various environmental and health problems if treated inappropriate. Landfill is the main or even the only mature technology for waste treatment in many countries. However, this technology is not well aligned with the sustainable development goals, because it usually occupies large amount of precious urban space, causes high risk of land and groundwater contaminations due to the release of heavy metals and toxins into the environment, and poses great challenges for persuading the local residents to accept the choice of building landfill plants nearby. Waste valorisation relying on chemical or biochemical processes for energy/products production with the expectation of zero waste generation has been recognized as a promising way for waste treatment and management. Comparing with the traditional waste treatment technologies, waste valorization can efficiently use waste for the production bioenergy, materials or some other chemical products, and it can not only successfully solve the environmental and health problems caused various kinds of waste, but also convert waste into useful products. The benefits are found both locally (i.e. air pollution mitigation, resource security and public health) and globally (i.e. greenhouse gases emissions mitigation). However, the cost-effectiveness and sustainability of the waste valorization processes is still debatable. Each waste valorization technology/process requires fossil fuels, and there are usually various kinds of waste emissions (i.e. CO2, NOx, SO2 and particulate matters, etc.) during the whole life cycle of the products produced in waste valorization processes. Therefore, innovations on waste valorization technologies for less consumption of fossil fuels and less negative environmental impacts are prerequisite. Meanwhile, there are a variety of different waste valorization scenarios, e.g. incineration, digestion, gasification and fast pyrolysis, etc. It is usually difficult for the decision-makers to select the most sustainable waste valorization option, improve the sustainability, and plan the infrastructure configuration of waste valorization supply chains.

In order to promote the concept of sustainability and sustainable development in waste valorisation, this special issue focuses on waste valorisation for sustainable production, process and products, and it aims at giving the readers a comprehensive view of technologies and processes for waste valorisation, presenting the life cycle tools for evaluating the economic performances, environmental impacts and social influences of different waste valorisation technologies/processes, and providing the methods for selecting the most sustainable waste valorisation scenario under various different conditions. Moreover, it also aims at developing engineering operations tools for providing the decision-makers/stakeholders insights and implications for promoting sustainable development of waste valorisation industry.
