Though the magnitude of organic-rich agri-food waste arisings from open-air markets in many sub-Saharan Africa cities such as Kampala, Uganda are largely unknown, predominant approaches to managing them, i.e., open burning and unsanitary landfilling, unsustainable, emitting greenhouse gases, represent an inefficient use their intrinsic compositional energy value. This study combined waste-to-en...

One of the more promising processes for the energetic transformation of waste is the anaerobic digestion of the Organic Fraction of Municipal Solid Waste (OFMSW). An experimental campaign was carried out on three different samples of OFMSW from Waste Separation (WS), one as received and two obtained after mechanical treatment (squeezing): OFMSW slurry (liquid fraction) and OFMSW Waste (residual...

The efficiency of methane production by anaerobic digestion (AD), during which energy is generated from organic waste, can be increased in various ways. Recent research developments have the volume gas AD using biochar. Previous studies used food waste itself AD, or, added wood-biochar or sewage sludge charcoal as an accelerant process. application food-waste biochar activated has not yet been ...

anaerobic digestion is a feasible technology to stabilize the solid waste generated inslaughterhouses obtaining significant quantities of biogas, considered as a clean and renewable fuel. this iswhy it is important to optimize the digestion process in order to eliminate organic matter and maximize theproduction of biogas. in this work, a system was developed for treating slaughterhouse solid wa...

a study of the biokinetics of anaerobic digestion of municipal solid waste (msw) was carried out using anaerobic batch digester. from the experimental results, the kinetic parameters (coefficient values) of the digestion of the msw were determined. the maximum rate of substrate utilization (k), saturation constant (ks), endogenous decay coefficient (kd), biomass yield or microbial growth yield ...

This paper provides an extensive review of anaerobic digestion (AD) systems, with a specific focus on community scale digesters for urban applications, processing either municipal organic waste exclusively or as mix feed. Emphasis is placed on reducing the systems scale environmental impact of AD technologies, including pre-and post-treatment stages, alongside biogas production. Developments to...

The supplementation of lignocellulose-degrading enzymes can be used to enhance the performance biogas production in industrial plants. Since structural stability these enzyme preparations is essential for efficient application, reliable methods assessment are crucial. Here, a mass-spectrometric-based assay was established monitor enzymes, i.e., integrity proteins, anaerobic digestion (AD). anal...

Wastewater and sewage sludge contain organic matter that can be valorized through conversion into energy and/or green chemicals. Moreover, resource recovery from these wastes has become the new focus of wastewater management, to develop more sustainable processes in a circular economy approach. The aim this review was analyze current management systems Scandinavia with respect recovery, combina...

Anaerobic digestion (AD) of sewage sludge can be optimised by adding trade wastes (TWs) because their nutrient content and boost in biogas formation if non-inhibitory. However, some components TWs might have an inhibitory impact, such as nitrogen compounds, sulphate, heavy metals, metalloids, halogens organic pollutants (e.g., phenol). This study aimed to understand the impact on co-digestion w...
