Special Issue Information

Dear Colleagues,

Sustainable development has been increasingly discussed due to climate change and the other environmental impacts of various production processes regarding waste generation, effluents, and emissions. The extraction of raw materials for the most diverse production sectors has become a significant environmental problem, not only due to the recurring environmental impacts of the extraction process but also due to the inadequate disposal of waste generated in the respective production processes. Waste valorization attempts to reuse and give a more noble destination to these materials that can, depending on their chemical and mineralogical compositions, replace traditional raw materials that are commonly sold, including gains in the product’s properties. In the same way, efficient resource and waste management can reduce the quantities of materials sent to landfills.

This Special Issue aims to collect new ideas of research on the topic of “Waste Valorization and Management to Increase the Resources Sustainability”. In this sense, works that involve waste characterization and the development of programs and actions aimed at waste management are included in this special edition. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • New strategies and guidelines to improve waste management systems;
  • Chemical and physical waste characterization;
  • Waste valorization in new sustainable materials;
  • Implement data analytics to study recycling patterns in waste management;
  • Innovative approaches for the recovery of landfilled wastes;
  • Life cycle and carbon footprint analysis of waste.

We look forward to receiving your contributions.

When designing settlements according to the “Green Building” principle, it is necessary to develop a heating system based on climatic conditions. For example, in areas with a sharply continental climate (cold and prolonged winters), it is sometimes necessary to use solid fuel boilers (in the absence of gas). However, to use these, it is necessary to use biomass or biomass-coal blends as fuel to increase their combustion heat. The addition of biomass waste to coal can be aimed at achieving various objectives: utilization of biomass waste; reduction of solid fossil fuel consumption; improvement of environmental performance at coal-fired boiler houses; improvement of the reactivity of coals or to improve the technical and economic performance of heat-generating plants due to the fact that biomass is a waste from various types of production, and its cost depends only on the distance of its transportation to the boiler house. In this work, combustion of various biomass wastes, including sewage sludge, was carried out on a fire bench emulating the operation of a boiler furnace. Fuel particles were ignited by convective heat transfer in a stream of hot air at a velocity of 5 m/s in the temperature range of 500–800 °C, and the experimental process was recorded on a high-speed, color video camera. The obtained values were compared with the characteristics of different coals used in thermal power generation (lignite and bituminous coal). The aim of the work is to determine the reactivity of various types of biomass, including fuel mixtures based on coal and food waste. The work presents the results of technical and elemental analysis of the researched fuels. Scanning electron microscopy was used to analyze the fuel particle surfaces for the presence of pores, cracks and channels. It was found that the lowest ignition delay is characteristic of cedar needles and hydrolyzed lignin; it is four times less than that of lignite coal and nine times less than that of bituminous coal. The addition of hydrolysis lignin to coal improves its combustion characteristics, while the addition of brewer’s spent grain, on the contrary, reduces it, increasing the ignition time delay due to the high moisture content of the fuel particles.
