“…A total solid concentration of 15.2% has been reported to lead to the highest yield of gas, but in case of fresh cattle dung employed as a mono substrate, it has to be mixed with water on a unit volume basis (1/1, water / dung) before feeding into the digester [21]. Mumme et al [32] have documented that hydrolysis of complex organic matter into soluble compounds is the rate-limiting step of anaerobic processes for wastes with a high solid content, and according to Charles et al [33] various physical, chemical, and enzymatic pre-treatments are required to avoid the challenges/difficulties due to the hydrolysis of lignocellulosic materials and increase substrate solubility; on the other hand, AD has some disadvantages such as long retention times and low removal efficiency of organic compounds [34]; furthermore, it can cause some traffic problems, health and safety risks because of the pathogenic contents of feedstock/digestate, some explosion risks, and visual impact due to the large tanks. So the AD plants have to be placed and designed in a way that eliminate all previous risks and the digestate has be treated to become pathogen-free and stable with low odor [35].…”

“…There are two types of fermentation, wet (10-25% dry matter), which is the most commonly used technique, and dry (30-40% dry matter) [36], which is an emerging process [34]. AD can be either single-stage (all reactions take place in one chamber) or multiple stage (reactions take place separately) [37].…”

“…Biogas production becomes maximum when anaerobic digestion method is applied. In this method the organic biomass waste is degraded or biologically transformed by diverse microorganisms, and convert the biomass waste into biogas [53], [54]. The biofuels resulted from the anaerobic digestion can then be utilized as a replacement for fossil fuels, and as these products are carbon neutral so they reduce carbon dioxide emissions to the environment, this process involves four main stages, these are (1) Hydrolysis, (2) Acidogenesis, (3) Acetogenesis, and (4) Methanogenesis [109].…”

-Lignocellulosic Biomass is considered to be the best option for biofuels production, due to the energy and food security concerns comparative to the use of other wastes, but this biomass has limited digestibility due to many factors like particle size, crystallinity of cellulose, lignin content etc. Pre-treatments enhance the digestibility by reducing the effect of these factors. Different pretreatment types exist, but now microwave pretreatment (individual or combined with other pretreatments) is becoming common due to its better results. This paper reviews the advantages of using lignocellulosic biomass in terms of the biofuels obtained from it, common pretreatments applied on it, and the effects of microwave pretreatments (individual and combined) over it.

Kitchen is the important part of house which take cares about the health of family members. It also generates organic wastes which are generally dumped. On the other hand many people felt shortage of animal dung for biogas production. This study is an attempt to find out the way between these situations by finding the suitability of kitchen wastes addition for biogas production. The experiment was performed in 5L glass bottles with two treatments i.e. buffalo dung alone and mixture of dung with kitchen wastes. The bottles were filled on daily feeding basis by the feeding material at 5.3% total solids for the experimentation period of 80 days. On first day 12mL fresh digested biogas slurry from running biogas plant was also added in all the digesters as inoculum. Daily biogas production was measured by water displacement method. Results show that co-digestion of dung and kitchen wastes produces 85.71 to 195.12% higher biogas than dung alone. Overall it produces 2.69 % higher total biogas than buffalo dung alone for the experimentation period of 80 days.
