Mapping of the Use of Waste as Raw Materials for Biogas Production

Abstract

Anthropic methane emissions can largely be prevented or minimized using technologies that are already available. One such technology is anaerobic digestion (AD), which is used commercially around the world, especially in Europe and the United States, where some challenging targets have been set to diversify the energy mix with more renewable energy. This foresight study was designed to identify which technological solutions out of the many options available for biogas production are attracting most interest, for which purpose patent documents and scientific publications were analyzed. The aim is to identify which raw materials are most attractive for AD and biogas production. It was found that the raw materials that have attracted most research and patenting activity are sludge, sewage, and wastewater, livestock waste, and agriculture waste, which together account for 62% of all the patents filed and 74% of all the scientific publications. The countries most engaged in producing biogas from AD plants are China, Germany, and the United States. We also identified a rising trend in the use of biogas around the world, and a steady increase in the number of patents filed on the subject, especially in Japan and South Korea. This growth is driven, amongst other things, by strategic governmental actions, global environmental pacts, and the realization on the part of industry that anaerobic digestion can be used as an efficient method for treating waste and effluents.

“…They also outlined biological methods like composting, micro aeration, and container closure to optimize biogas production. Grando et al (2017) surveyed raw materials commonly used for biogas production, such as sludge, biological waste, wastewater, livestock waste, and agricultural waste. Awe et al, (2017) demonstrated that is an effective renewable energy sources for fuel and chemicals production, including hydrogen and synthetic gas.…”

Biogas Production from Food Waste Using Nanocatalyst

“…Different wastes were used as a raw material for the biogas production such as algae with aquatic plants, industrial waste, municipal solid waste, food waste, cellulosic waste, agricultural waste, livestock waste, and sewage sludge. Among the above, sewage sludge has a predominant source [19]. Mixture of different raw materials was also used for the biogas production such as cow dung, pig manure, cow urine, and fecal matter [7].…”

“…biogas consists of methane (50-75%), carbon dioxide (25-50 %), as well as small amounts of other gases such as nitrogen (0-10%), hydrogen (0-1%), hydrogen sulfide (0-3%), and oxygen (0-2%) [10]. the biofuel is renewable and environmentally clean which significantly decreases the fossil fuel consumption [11]. Anaerobic digestion is a useful energy production technique.…”
