“…Gelatin can also be produced from wastes from industry and farming [8]. Composting (C), a biological treatment through which organic wastes are converted into valuable humus [9], is a widely accepted technology for the recycling of organic waste. However, the composting process not only emits large quantities of greenhouse gases (GHGs), but also malodor and leachate imposed environmental pollution, and compost is not stable in the soil for a long time.…”

Physio-Chemical Characterization of Biochar, Compost and Co-Composted Biochar Derived from Green Waste

Organic wastes are naturally biodegradable, but they contribute to environmental pollution and management issues. Composting and pyrolysis are widely used technologies for recycling these wastes into valuable organic products for soil health and crop production. In the current study, fruits vegetables waste (FVW) was converted to biochar, compost, and co-composted biochar. The microcrystal structure, functional groups, surface morphology, and nutrient contents of organic materials were investigated by XRD, FTIR, SEM-EDS, AAS, multi C-N analyzer, and ICP-OES techniques. Heavy metals contamination was not detected in the biomass used for pyrolysis and compost preparation. FVW had an acidic pH (5.92), while biochar, compost, and co-composted biochar had an alkaline pH. Total macronutrient (K, Na, S) and micronutrient (Cu, Fe) concentrations were higher in compost and co-composted biochar, with the exception of K, which was higher in biochar. Biochar had the highest surface area (4.99 m2g), followed by FVW, compost, and co-composted biochar. Co-composted biochar had a porous structure. Si, Ca, and Al contents were common in all organic materials, while P, K, Mg, and S were found with lower concentrations in both biochar and compost. Iron was only found in compost and co-composted biochar. Quartz, sylvite, and calcite were common minerals found in all organic treatments. Biochar contained more aromatic carbon ring structure C=C/C=O and aromatic C-H bending as compared to FVW and compost, thus, making biochar a stable carbon rich material suitable for soil carbon sequestration.

“…From those, it is important to highlight the impact of periodic training on all the employees and the community involved with the WWTP, as it leads to a better appropriation and knowledge of the system, resulting in a more proper operation of the processes carried out in the WWTP, with the final endpoint being an improvement in the decision-making of the WWTP [51,52]. Likewise, the environmental incentives (EI) for the management of sludges and biosolids became relevant in Colombia as governmental parties have encouraged companies to implement national policies which lead to better conversion and good use of biosolids and sludges [53][54][55].…”

Identification and Evaluation of Determining Factors and Actors in the Management and Use of Biosolids through Prospective Analysis (MicMac and Mactor) and Social Networks

The reuse of biosolids in agriculture and its inclusion within the circular economy model requires evaluating and analyzing factors that intervene in its management. The objective of the study was to analyze those factors that influence the management and use of biosolids. Fifty-three actors were questioned, and their answers were analyzed using two prospective methods and Social Network Analysis (SNA) identifying between 14 and 19 variables. Six should be prioritized due to their criticality and potential in management and reuse scenarios. It was observed that the formulation of objectives, such as the improvement of infrastructure, creation of an institutional policy, and the establishment of definitions for the kinds of biosolids, are opposed by internal agents. Seven key actors and four to six determining agents were identified in the scenarios. The network of management and use of biosolids in agriculture presented low density (0.28) and the exclusive action of three key actors. Consequently, the participation of a greater number of better-connected actors is required to project networks with a higher density (between 0.49 and 0.57), facilitating the diffusion of information and the inclusion of new actors not previously contemplated. The application of prospective and SNA methodologies focused on biosolids allows the prioritization of determinants, the evaluation of the level of involvement and communication between actors, and other aspects that have not been considered previously in the management of WWTPs in Colombia.

“…The 'reclamation of eroded soil patches and mineral fertilization' by primary-undigested and secondary-digested municipal biosolids (MBS) rich in organic C-and N-compounds was often pursued systematically (Brown and Chaney 2000;Kashmanian et al 2000;Mishra et al 2005aMishra et al , 2007. Thus, organic fertilization of soil, concomitant with FA remains a desirable/sustainable means of utilizing FA in commercial rice farming since, FA is waste without any C-or N-compound.…”

Rice was grown in soil co-amended with coal fly ash (FA) with municipal biosolids (MBS) to study the accumulation of heavy metal (HM) in rice seeds from FA with the co-amendment of MBS. Element-analyses of soil samples, plant-roots and seeds revealed the accumulation of HMs, Fe, Mn, Ni, Co, Zn, Cu and Pb proportionate to the FA doses. For ascertaining some suitable amendment-doses for maximal grain yield with the least accumulation of HMs, principal component analysis (PCA) was carried out with data from three rabi (winter) seasons. With PCA, the variance of performance of FA and MBS together was obtained, 87.25%. It could be concluded that the double amendment levels up to 10 Mg ha −1 FA + 7.5 Mg ha −1 MBS would be the desirable on soil with the accumulation of Pb12 ppb; nonetheless, the toxicity from other HMs was noted at the level 12 mg Mg −1 in rice grains.
