Project: GCOS Earth Heat Inventory - A study under the Global Climate Observing System (GCOS) concerted international effort to update the Earth heat inventory (EHI), and presents an updated international assessment of ocean warming estimates, and new and updated estimates of heat gain in the atmosphere, cryosphere and land over the period from 1960 to present. Summary: The file “GCOS_EHI_1960-2020_Inland_Water_Heat_Content_data.nc” presents an updated estimate of the global heat storage within natural lakes and artificial reservoirs for the period 1960-2020. Several improvements have been implemented in comparison with Vanderkelen et al. (2020): new approach to estimate lake volume, new lake models considered, and an extension of the analysis period. The data are used in von Schuckmann et al. (2022).

In this work, we conducted a study that is to bleach wastewater model solutions loaded with dyes of indigo and sulfur black, while using and optimizing the process of hybridized treatment of textile effluents by torque of coagulation-ultrafiltration (CO-UF). According to the separate optimization of coagulation processes (optimum dose of the coagulant (lime) and ultrafiltration membrane (hydrodynamic characterization of the membrane based on polysulfone (PSU)), we combined the two methods in order to increase performance fading exploited colored waters. The results of the rate of discoloration separated by the methods of coagulation and ultrafiltration are respectively of the order of 33.55% and 80.36% for the water loaded with indigo and of the order of 25.33% and 60.78% for those charged with the black sulfur. While the results of the bleaching obtained by the hybrid method CO-UF have shown that the bleaching rate was calculated as around 98% for the indigo and of the order of 92% for the black sulfur, obviously very interesting with respect to the coagulation and ultrafiltration used separately.

Description of the subject. Extracellular enzymes from filamentous fungi are increasingly used in eco-friendly biotransformation processes. Their relevant technological role and their stability towards extreme process conditions make of them the first sustainable solution for the elaboration of bio-based products from biomass conversion. Objectives. This paper describes the isolation of filamentous fungi from decaying plant material in the region of Meknes (northern central Morocco) and the assessment of their ability to breakdown lignocellulose. The objective is to select performant fungi with enzymatic machinery adapted to local environment and with potential for the breakdown of the regional specific lignocellulosic by-products into potentially high-value molecules. Method. Cereals, decaying wood, olive-pomace and -pulp and their composts were used to isolate lignocellulolytic fungi. One hundred twenty-seven pure strains were isolated and screened at 25 °C on selective media with cellulose or lignin as the sole carbon source. Performant strains were validated for the production of ligno-cellulolytic enzymes and identified using molecular technique. Results. Twenty-eight fungi had mycelial diameter on cellulose ≥ 6 cm and cellulolytic index ≥ 0.9. Twenty-two strains had the same profile on lignin medium. The production of endoglucanase, lignin peroxidase and manganese peroxidase enzymes was confirmed in performant strains using qualitative assay and molecular identification revealed that the best performing fungi were Mucor circinelloides, Mucor racemosus, Penicillium brasilianum, Penicillium crustosum, Paecilomyces sp., Fusarium oxysporum, Fusarium solani, Aspergillus fischeri, Curvularia spicifera, Humicola grisea, Trichoderma atroviride and Cosmospora viridescens. Measurement of ligno-cellulolytic activities revealed that Penicillium and Fusarium strains mainly from wood decay and compost had the best profiles among performing strains. Conclusions. Isolated fungi are high decomposers of biomass and represent a prominent solution to develop green bioprocesses in the region.

The research deals with problems of animal waste potential usage in order to produce biogas for energy generation in Ukraine. Although there are favorable conditions to develop biogas sector based on animal waste, the share energy, produced from it, is extremely low. The paper analyzes energy potential of agricultural biomass in Ukraine, economic tools, aimed at stimulating electricity generation from biogas based on animal waste, the results of their impact on biogas plants deployment. Among a number of barriers, which inhibit the development of this sector in Ukraine, the main ones are the need for significant initial investments to construct profitable biogas plants and a large amount of raw materials for their uninterrupted operation. Given the fact that 48.2% of farm animals are concentrated in small-scale farms and households, which cannot individually implement biogas projects, it is proposed to combine their financial and raw material resources within energy co-operatives. Economic benefits, which may be gained by small-scale farms within energy co-operative through the sale of electricity, generated from biogas, by feed-in tariff are calculated. It is discussed that in addition to economic benefits for small-scale farms owners, realization of the co-operative model in the bio-energy sector will let to obtain a number of ecological and social benefits both for territorial communities, and the state as a whole.

The use of Urea–Ammonia Mixture (UAM), 32% contributes to an in–crease in the productivity of agricultural land, with a decrease in the cost per unit of production of fodder and other crops. The composition and ratio of components, UAM, 32% contains three forms of nitrogen–ammonia (25%), amide (50%) and nitrate (25%), due to which the fertilizer acts for a long time, and vegetative alfalfa plants are provided with nitrogen throughout the growing season of the crop. The cost of nitrogen in UAM, 32% is the lowest, since its losses when using UAM, 32% on alfalfa do not exceed 10% of the total content. When applying UAM, 32%, the stability of organic diversity, characterized by a positive evolutionary process and adaptability of a complex of organisms associated with external factors of the environment without violations of the ratios of dominant species of organisms, was established. UAM, 32% does not affect levels of global biodiversity, with abiotic levels of agrocenoses, which provide optimal indicators of the circulation of substances, energy and information, as well as mechanisms for preserving the ecological niche and conditions for the existence of a diversity of biota.

Conversion of waste biomass to resource, through the environmentally sound multipurpose process of anaerobic digestion, allows the sustainable organic waste management, bioenergy and biofertilizer production, and therefore facilitates the transition to circular economy and mitigation of environmental pollution. The goal of this study was to assess and compare the agricultural performance parameters of biogas residues (BRs) and chemical fertilizers (CFs) while monitoring the residual nitrate accumulation under repeated application on a grassland in the Walloon Region of Belgium over the period 2013-2018. The results showed that BRs produced the same yield as CFs and could lead to similar N uptake after five years of application. Nitrogen fertilizer replacement value (NFRV) of BRs tended to increase over time, while in the last year of the experiment raw digestate demonstrated a NFRV of 99.9% in substitution for ammonium nitrate. The high nitrogen rate tested inhibited N uptake and yield for both BRs and CFs. Finally, BRs did not cause significant nitrate accumulation in the soil compared to CFs while repeated application of CFs indicated a cumulative effect. These results strongly advocate for the agricultural and environmental benefits of BRs and underline their suitability as substitutes for CFs in similar grassland systems.

A combination of simultaneous thermal analysis, evolved gas analysis and non-ambient XRD techniques was used to characterise and investigate the thermal decomposition behaviour in the NH3 − UO3 − H2O class of materials. One compound was prepared according to a typical ammonium diuranate precipitation reaction, and could be identified as 3UO3·NH3·5H2O. Microspheres prepared by the sol-gel method via internal gelation were associated to the composition 3UO3·2NH3·4H2O under the specified conditions. The products were analysed using the techniques listed below, the resulting data are part of this dataset.
