Special Issue Information

Dear Colleagues,

Waste management constitutes one of the most critical aspects in the modern world. Due to the rapid growth of urban population over the years, as well as the changing consuming habits and lifestyle patterns of societies around the globe, solid waste management has emerged as one of the most important pressures on the natural environment. In parallel, the environmental concerns of people are constantly increasing, with citizens across the world “demanding” environmentally sound management of solid wastes. Undoubtedly, due to the complexity of the problem under study, there is not a single waste management option available that can provide a holistic solution for all different kinds of waste streams generated (e.g., municipal solid waste, industrial waste, bio-waste, waste electrical and electronic equipment, construction and demolition waste, end-of-life vehicles) and globally satisfy the needs of different populations with diverse characteristics, customs, and habits. To that end, different, alternative processes, technologies, and strategies ought to be developed and proposed, so as to cover the high requirements for efficient waste management in a number of topics (e.g., waste generation, characterization, collection, separation, treatment, and final disposal). In this light, integrated waste management strategies are considered as a prerequisite towards sustainability.

The present Special Issue, entitled “Integrated Waste Management”, seeks to provide information and evidence on the field for researchers, practitioners, and/or policy-makers, as well as to contribute to the waste management agenda through enhanced scientific and multidisciplinary knowledge to boost the performance efficiency of waste management and support policy-making. To that end, we invite papers on innovative technological developments in the field, as well as reviews and pilot studies that demonstrate new knowledge and near-to-market solutions within the area of integrated waste.

Leaching of Chlorides, Sulphates, and Phosphates from Ashes Formed as a Result of Burning Conventional Fuels, Alternative Fuels, and Municipal Waste in Household Furnaces

The aim of the study was to assess leaching of Cl, SO42−, and PO43− from ashes formed in household furnaces. The ashes were obtained following the combustion of conventional fuels, namely wood and hard coal, and alternative fuels with various fractions of municipal waste in a household boiler. Aqueous leachates of the ashes were used to determine concentrations of chlorides by titration (Mohr’s method) (21.3–3049.6 mg/dm3), sulphates by the gravimetric method (12.2–244.1 mg/dm3), and phosphates by spectrophotometry (0.01–67.2 mg/dm3). It was found that co-combustion of municipal waste with plastic-coated paper cartons, diapers, or a mixed waste fraction leaves the greatest amount of ashes on the furnace grate. The highest amounts of Cl, SO42−, and PO43− were leached from ashes generated from burning a mix of wood and coals, or wood alone (different species). The addition of municipal waste to the process of burning the conventional and alternative fuels studied did not significantly increase Cl, SO42−, and PO43− content in aqueous extracts of ashes, the exception being diapers and plywood. In light of the study results, it was concluded that all the ashes could be reused (as an additive to concrete) except for the ash generated from the combustion of a mixed municipal waste fraction and coal (due to the content of Cl) and diapers (due to the content of PO43−). It was demonstrated that Cl, SO42−, and PO43− content in the entire set of samples and in individual ash groups is highly heterogeneous and variable. Full article

Significant amounts of produced water, spent drilling fluid, and drill cuttings, which differ in composition and characteristics in each drilling operation, are generated in the oil and gas industry. Moreover, the oil and gas industry faces many technological development challenges to guarantee a safe and clean environment and to meet strict environmental standards in the field of processing and disposal of drilling waste. Due to increasing application of nanomaterials in the oil and gas industry, drilling wastes may also contain nanometer-scale materials. It is therefore necessary to characterize drilling waste in terms of nanomaterial content and to optimize effective methods for their determination, including a key separation step. The purpose of this study is to select the appropriate method of separation and pre-concentration of silver nanoparticles (AgNPs) from drilling wastewater samples and to determine their size distribution along with the state of aggregation using single-particle inductively coupled plasma mass spectrometry (spICP-MS). Two AgNP separation methods were compared: centrifugation and cloud point extraction. The first known use of spICP-MS for drilling waste matrices following mentioned separation methods is presented.

Despite the technology for wood biomass combustion being much more advantageous when compared to traditional burners, such as the Stoker or fluidized burner, there has been scant research on the topic of wood biomass cyclone burners. The purpose of this paper is to review biomass cyclone burner technology, which includes theory, design, and combustion, in terms of the chemistry and properties of wood biomass, emission related to NOx and CO, and application of the burner, such as co-firing with coal and gasification firing. The design factors for type 2 cyclone burners have been identified through the following three dimensionless numbers: swirl intensity (S), Strouhal number (St), and Reynolds number (Re). The lowest CO and NOx of type 2 cyclone burners have been sought for pulverized and non-pulverized wood biomass. The benefits of the co-firing of wood biomass in a cyclone burner with coal, have been presented in respect to combustion efficiency, alkali retention, and the amount of K and Na. The results evidently reveal the reduction in clinker and slag generation, which are the biggest concern to wood biomass combustion. The recent results of gasification studies using type 2 cyclone burners are compared, in terms of producer gases and syngases (H2, CO, CO2, CH4). Full article
