“…This systematic review focuses mainly on the techniques most suitable for the bioremediation of specific pollutants such as heavy metals, hydrocarbons, polymers and their derivatives, and finally organic pollutants. In the wider applicability of the studies mentioned here, it was found that the use of microbial consortia for the bioremediation of heavy metals [11][12][13][14][15][16] and hydrocarbons [17][18][19][20][21][22][23] gave satisfactory results with significant removals. For the biodegradation of polymers, it was found that certain bacterial strains were able to biodegrade plastics in soil [19,[24][25][26][27][28], in contrast to other studies that used bacterial consortia [29][30][31][32], resulting in a significant reduction in these contaminants as well as a reduction in biodegradation time by 90 days [30] and 30 days [31], demonstrating that the symbiotic capacity of bacteria can be a viable option.…”

“…Eighteen percent of the studies listed in Table 6 address the bioremediation of soils contaminated with hydrocarbons, and although they use different strategies, all conclude that bioremediation is a viable and effective option for removing this type of contaminant. Most of these studies investigated the degradation capacity of this type of contaminant using bacterial consortia [17][18][19][20][21][22][23], which produced effective results in the removal of aromatic hydrocarbons and volatile organic compounds. In other studies, the degradation capacity of specific bacterial strains was evaluated by isolation and inoculation [132], showing a pollutant degradation capacity of up to 81% after 60 days [111].…”

This systematic review presents the current state of research in the last five years on contaminants in soils, especially in leachates from solid waste landfills, with emphasis on biological remediation. In this work, the pollutants that can be treated by microorganisms and the results obtained worldwide were studied. All the data obtained were compiled, integrated, and analyzed by soil type, pollutant type, bacterial type, and the countries where these studies were carried out. This review provides reliable data on the contamination of soils worldwide, especially soils contaminated by leachate from municipal landfills. The extent of contamination, treatment objectives, site characteristics, cost, type of microorganisms to be used, and time must be considered when selecting a viable remediation strategy. The results of this study can help develop innovative and applicable methods for evaluating the overall contamination of soil with different contaminants and soil types. These findings can help develop innovative, applicable, and economically feasible methods for the sustainable management of contaminated soils, whether from landfill leachate or other soil types, to reduce or eliminate risk to the environment and human health, and to achieve greater greenery and functionality on the planet.

This paper reveals the linear economy contribution to resource degradation and environmental pollution in eastern Romania that could further feed environmental crimes and conflicts, such as in the Pungesti shale gas case. Preservation of material and water resources in the region is required through various circular mechanisms under a cross-sectoral approach including solid waste as a material resource for industry and agriculture; wastewater treatment and water reuse; composting and organic agriculture; and using renewables. Six non-conflictual sustainable alternative routes related to circular economy mechanisms, water preservation, and to the clean energy transition are proposed in this paper, which are further examined through key statistics and indicators, current best practices, and local development pathways in both urban and rural communities.

“…Furthermore, the Autonomous Community of Valencia, by means of Regional normative 5/2022, established specific management measures for biowaste, including its separation and recycling through biological treatment, including treatment at the source through community composting, to obtain quality organic amendments [11]. Thus, new paradigms have appeared, where the treatment of different organic waste fractions by composting, such as those from household waste streams, garden and park waste and remains from fresh product markets (biowaste), is carried out locally using decentralized models, such as community composting [12]. However, currently, there is a lack of standardization concerning the control of the process and of the final product in these new composting scenarios, which is essential to guarantee the agronomic value, degree of stability and maturity, product quality and especially the hygienic conditions of the compost obtained [13] for its use in agriculture.…”

Over the last several years, the models for organic waste management have changed to implement circular economy in the productive cycle. In this context, new scenarios have emerged, where the management of different organic waste streams by composting is conducted with decentralized models that manage organic wastes in a more local way. However, in these new models, the standardization of the process control and of the end-product characteristics is necessary to guarantee the quality and agronomic value of the compost obtained, avoiding potential risks for human health and the environment. Thus, the aim of this work was to study two different scenarios of community composting of the organic fraction of municipal solid waste separately collected in order to guarantee the effectiveness and reproducibility of the composting processes and the quality of the composts obtained. For this, the development of the process and the characteristics of the composts at agronomic, hygienic–sanitary and environmental levels were assessed in real conditions and during three cycles of the process. The results obtained show high similarity among the different composting cycles, indicating an important degree of reproducibility among the processes. In addition, the composts obtained showed a good sanitary quality, absence of phytotoxicity and low contents of potentially toxic elements, which guarantee their use in agriculture without posing any risk to human health and to the environment.
