Recycling Centre – The Ball Mill. The Ball Mill is responsible for diverting approximately 70% of wheelie bin waste from landfill and is the only one of its kind in the UK at present. The Ball Mill is a huge drum similar to a washing machine that contains 42 tonnes of steel balls. Leicester city’s waste is fed into the drum, which rotates

Anaerobic digestion (AD) is a process of degradation of organic matter by microorganisms in an oxygen-free environment, which produces biogas, a vital renewable energy source. Using solely an organic source, such as monosubstrates, it is difficult to optimize the AD process due to nutrient imbalance, lack of appropriate microbial communities

Effect of pH on Biogas Production:- pH affects the growth of microbes during anaerobic digestion of biomass to produce biogas. According to Sreekrishnan et al. (2004), the pH of the digester should be kept within a desired range of 6.8-7.2 by feeding it at an optimum loading rate to obtain a higher yield of biogas.

Ball-mill pretreatment also increased the total volatile fatty acids. During the anaerobic digestion (AD) of ball-mill treated food waste, acetoclastic methanogens predominated, with a relative abundance of 48–49%. Interestingly, hydrogenotrophic methanogens were 1.6 times higher in the pretreated samples than those in the control.

Similar to microaerobic pretreatment before the anaerobic digestion process, the oxygen supply in STMT during anaerobic digestion process not only reduces the concentration of toxic metabolites (e.g., ethanol, acetic acid and lactic acid) but also promotes the synthesis of certain lipids required for the stability of the anaerobe cell membrane (Fu et al. 2015c) as shown in Table 2.

2. Stages of Anaerobic Degradation of Organic Wastes. Microbiology of anaerobic transformation of organic wastes is a process which involves many different bacterial species, such as hydrolytic, acid forming, acetogenic, and methanogenic bacteria which produce CO 2 and CH 4 as the main products of the digestion process [11, 12].

Unlike in wastewater treatment, anaerobic digestion of mill biosludge (waste activated sludge) and primary sludge is still in its infancy. Current research is mainly focused on developing efficient pretreatment methods that enable fast hydrolysis of complex organic matter, shorter sludge residence times and as a consequence, smaller sludge digesters.
