The study presents research focused on factors influencing performance in municipal solid waste management (MSWM) at the level of individual municipalities in the Czech Republic. Czech municipalities possess a specific municipal structure that is characteristic of high fragmentation, in which municipalities spatially resemble conglomerates. In spite of their typically small size, they cling to their own independence and are thus willing to assume full responsibilities in MSWM. In recognition that expenditure on MSWM is the primary concern to municipalities and that there are secondary environmental interests in waste separation, four alternative models of waste management service production are considered for a sample of 470 Czech municipalities that capture performance from different standpoints. Performance in MSWM is assessed by dint of data envelopment analysis (DEA). Full frontiers are employed simultaneously with order-m partial frontiers and resulting unconditional-to-conditional scores are investigated for the influence of twelve contextual factors describing operating conditions of MSWM. The analysis accounts for the fact that in this case the twelve contextual factors are found non-separable from the process underpinning the provision of MSWM. It is revealed that performance in MSWM improves with the availability of recycling consolidation facilities, but programs inciting waste separation or green waste collection do not bring about the anticipated effect. The findings are instrumental in planning of MSWM and equip municipalities with policy advice that is useful in improving performance in MSWM and subsequently in reaching ever stricter environmental targets requested over time at both national and international levels translated to a municipal level.

Aquaculture systems generate large amounts of sludge that represent serious environmental threats if discharged directly into local ecosystems. However, this nutrient-rich sediment can contribute to nutrient cycling by being applied as an organic fertilizer to ornamental medicinal trees during their early growth stages. To investigate the potential advantages of using recirculating aquaculture system sludge (RASS) and biofloc technology sludge (BFTS) as organic fertilization alternatives to chemical fertilization, a pot trial was conducted at the Faculty of Agriculture, Cairo University, Egypt.

In order to explore the management and treatment methods of solid waste in the Controlled Ecological Life Support System (CELSS) of future lunar bases, during the 4-crew 180-day integrated experiment, the Solid Waste Management and Treatment System (SWMTS) was built, in which the treatment of recyclable solid waste such as inedible plant parts and human excrement was completed through a combination of biological aerobic composting and high-temperature oxidation. Basic data on the types and amounts of solid waste generated during the 4-crew 180-day experiment mission were obtained. There were six types of solid wastes, including the work support wastes, the household support wastes, the plant cultivation wastes, the plant-based wastes, and crew feces.

Odor emissions, primarily from anthropogenic activities like waste treatment and industrial processes, pose significant challenges in urban areas, particularly near water resource recovery facilities. While these emissions are generally not toxic, they can adversely affect community wellbeing and investment, prompting stricter regulations in some regions. For example, New York State's hydrogen sulfide guidelines are more stringent than federal standards.

Two novel and unique adsorptive materials, one (Fluorolock®) from clay mineral sepiolite coated with the cationic polymer polydiallyldimethylammionium chloride (pDADMAC) and the other (Intraplex®) from colloidal activated carbon were specially developed for the in situ remediation of per- and polyfluoroalkyl substances (PFAS) in the saturated zone. We evaluated the potential of both materials to immobilize PFAS in soils under flow conditions via soil column experiments using groundwater, which was contaminated with PFAS in the field. Furthermore, the potential ecotoxicological effects of both materials on aquatic organisms were assessed by exposing the soil column effluent to Daphnia magna.

To investigate the potential of activated carbon from palm kernel shell waste for Tc-radiolabeled nanocarbon aerosol, a new production technology for carbon-based Tc-radioaerosol from such a waste was developed. Treated-palm shell charcoal (t-PSC) was prepared by hydrothermal method to increase the surface area, followed by Tc radiolabelling optimization. The optimal Tc radiolabeling conditions resulted in an adsorption capacity of 21.
