Municipal solid waste (MSW) management is a controversial aspect of isolated environments, not only because the production of waste grows exponentially, but also because in these isolated regions the difficulties are accentuated in comparison with the mainland territories. The limitation of space, the technology of scale and the peaks of generation due to existing tourism, are clear examples of the barriers that must be overcome. This research studies the potential of MSW recovery on the island of La Gomera (Canary Islands) as an alternative to landfill deposition, being an additional energy source for heat and electricity. Likewise, the possibility of carrying out the landfill mining located in the El Revolcadero environmental complex is explored. The methodology followed consists, first of all, on estimating the annual amount of MSW and waste deposited in the landfill. Second, the characterization of representative samples of each municipality is carried out. Third, according to these characteristics, the thermal treatment is chosen and, finally, the energy generated is evaluated. The results are encouraging, and many advantages are derived from this model. The annual recycling figure increases by about 5000 tons per year, the percentage of renewable energy from waste reaches 35.5% (most installed capacity is diesel), and greenhouse gases (GHG) are reduced by more than half. To overcome the challenges in the integral management of MSW, it is necessary to move from a linear economy to a circular economy that takes into account the priorities established by the European Union to solve the problem of these isolated environments in terms of energy.Union and the Spanish legal framework regarding the priorities of waste management: reducing combined municipal solid waste and increasing the selective collection of recyclable materials [6,7].There are many technological options available to reduce the waste generated [8]. The most usual procedures require thermal treatment (incineration, pyrolysis, gasification or plasma). However, other technologies have also been explored. Those based on anaerobic digestion and others that value waste, 'valorizing' it as an alternative fuel in thermal power generation installations. One of the most commonly considered options to reduce MSW is incineration or combustion. Indeed, one of the arguments used to seek support for incineration is that it generates energy that is presented as renewable. Poletto and Da Silva [9] argue that the controlled combustion of MSW is a definitive solution to the problem, when carried out in facilities with adequate air-pollution control devices. However, the reality is that it is necessary to attend to factors other than just air pollution, for example: impacts on water, soils, landscape, ecosystems and the urban areas themselves. In this context, sustainability consists of the evaluation of the environmental, economic and social impacts of the available waste treatment options [10]. In this sense, Cucchiella et al. [11] analyze a specific case in the ...

The circular economy is at the core of sustainable development. The generation of biogas from the massive quantity of agricultural waste biomass is one of the critical drivers of the circular economy. Biogas has enormous renewable energy potential and has multitudes of applications in today’s energy-intensive society. Oil cakes, a known Agri-waste, are the by-product of oil processing, and are rich in nutrients. The edible oil cakes mostly have been used as a cattle feed; however, non-edible oil cakes do not find many applications. Their production is continuously escalating as non-edible oils are increasingly used in biodiesel production. Recently, there is a lot of emphasis on biogas production from these oil cakes. This paper reviews in detail biogas production from both edible and non-edible oil cakes. Chemical composition and various other applications of the cakes are also reviewed in brief. The survey illustrates that multiple parameters such as inoculum sources, co-digestion and reactor design affect the biogas production. All those factors, along with biogas upgrading and the economy of the process, are reviewed. Finally, future research opportunities are suggested to improve the viability of the biogas production from oil cakes.

“…Since the literature has not yet been reported, therefore, liquid phase of pig manure was taken as the research object in this study, aiming at the degradation of organic matter in liquid phase of pig manure, the inactivation of pathogenic microorganisms and the development of biogas at different storage temperatures. This study was conducted on a laboratory scale and the objectives of this study were (1) to construct a low cost rapid anaerobic fermentation and biogas sewage storage system, (2) to provide a scientific basis for fecal sewage treatment and resource utilization in small and mediumsized aquaculture enterprises.…”

“…The generation and inappropriate management of animal manure cause serious environmental problems. Animal manure is usually spread on land near confined feeding operations, which leads to a series of problems, such as the contamination of surface water and groundwater with pathogens, odor emission, loss of a potential green energy source, accumulation of excess phosphate (PO 4 3+ ) in soil, and deterioration of biological ecosystems [2,3]. Anaerobic digestion technology is regarded as one of the most sustainable technologies due to its low energy consumption, high efficiency and new energy production in the process of treating livestock and poultry wastes [4].…”

A study was designed aiming at the degradation of organic matter in liquid phase of pig manure, the inactivation of pathogenic microorganisms and biogas production at different storage temperatures. A low cost rapid anaerobic fermentation, and biogas sewage storage system was constructed. After the four-day anaerobic fermentation, three treatments were set up: the average temperature of spring and autumn (16.1ºC), summer (25ºC), and winter (0.6ºC) in Yantai City was used as storage temperature for 90 days, respectively. The results showed that the biogas potential of anaerobic fermentation and biogas sewage storage at 16.1ºC and 25ºC was higher than that stored at 0.6ºC. During the experiment, total solids (TS) and organic matter contents in fecal sewage were decreased with time, and the value was determined at 25ºC. Total phosphorus and potassium contents in biogas sewage did not change significantly over time, but the total nitrogen content decreased. The content of the 5 day biological oxygen demand (BOD 5), the chemical oxygen demand (COD Cr) and suspended solid concentration (SS) in fecal sewage showed a downward trend over time. The egg mortality of Ascaris lumbricoides increased in different degrees under the three storage conditions. The number of E. coli in biogas sewage stored at 0.6ºC and 16.1ºC showed a downward trend, and the number of E. coli in biogas sewage stored at 25ºC was significantly higher than at 0.6ºC and 16.1ºC. The comprehensive analysis showed that at temperature 25ºC, the an-aerobically produced fecal sewage after fermentation had best potential for biogas production.
