“…Additionally, aerobic systems are available. Many recent studies analyzed the performance of CSTR for whey treatment in co-digestion with feedstocks of high nitrogen or solid matter content (Martínez-Ruano et al, 2019;Ramos-Suárez et al, 2019). In general, wastewater from dairies is treated microbiologically using both aerobic and anaerobic systems.…”

The food and beverage industry offers a wide range of organic feedstocks for use in biogas production by means of anaerobic digestion (AD). Microorganisms convert organic compounds-solid, pasty, or liquid ones-within four steps to biogas mainly consisting of CH 4 and CO 2. Therefore, various conversion technologies are available with several examples worldwide to show for the successful implementation of biogas technologies on site. The food and beverage industry offer a huge potential for biogas technologies due to the sheer amount of process residues and their concurrent requirement for heat and power. The following study analyzes specific industries with respect to their implementation potential based on arising waste and heat and power demand. Due to their chemical composition, several feedstocks are resistant against microbiological degradation to a great extent. A combination of physical-, chemical-, and microbiological pretreatment are used to increase the biological availability of the feedstock. The following examples will discuss how to best implement AD technology in industrial processes. The brewery industry, dairy production, slaughterhouses, and sugar industry will serve as examples.

“…Be that as it may, there are numerous difficulties, potential for investigating new waste streams, and holes for additional streamlining of the concerned procedures. Martínez-Ruano et al [20] utilized another mix of squanders, milk whey which is one of the essential buildups of the dairy business and potato stem, to deliver biogas by means of co-absorption approach. The two feed stocks are not great as individual substrate but rather their synergetic use demonstrated upgrades in biogas creation.…”

The integrated waste management method used to examine solid waste problems in different developing countries along with their solution. Integrated sustainable waste management includes examination of physical elements like assemblage, dumping, and reprocessing as well as government role like involvement of consumers and facility suppliers; financial stability; rational institutions supported by coherent guidelines. The data shows that the performance has enhanced considerably over past 10 years in different developing countries. The mean collection and disposal rate of disposal in the middle 95% are even more common than in the low-income cities, even before 50%. Recycling rates of 20–30% have been achieved by the informal sector in many low-income countries. The evidence suggests that efficient, effective, and inexpensive systems are compatible with local requirements and conditions, developed with the direct involvement of service recipients. Despite the remaining challenges, evidence from recent reforms suggests that sustainable solid waste and resource management are possible for developing countries. The articles distributed right now a wide scope of themes, including vitality recuperation from squander, waste to vitality advances, maintainable vitality frameworks, anaerobic absorption, warm circular segment plasma gasification, microalgal-based biorefinery, squander the board, displaying of cutting edge gasification frameworks, squander valorisation, and microbial power module innovation.

“…This review is based on 14 articles from diverse geographic locations. Some of these studies use discounted cash flow analysis while others are limited to costbenefit analysis [90,[92][93][94] and the other feedstocks such as milk whey, and energy crops [85,86,90,93,96,98]. Capacities reported in techno-economic analysis varied between 20,000 and 200,000 tons of annual processing capacity, while the CAPEX ranged between 25 and 165 M$.…”

“…Most of the studies reported that lack of incentivizing policies, high capital cost and low tipping fee are the critical barriers in the biogas-to-energy or biogas-to-fuel technologies [85,89,[93][94][95]. A study by Sanscartier [95] from Canada showed that with current feed in tariff (FiT) rate ($0.147/kWh), a 200 kt/yr co-digestion facility requires a $50/t tipping fee to attain an 11% IRR, while a 50 kt/yr facility requires a $95/t fee not accounting the revenue from digestate sales.…”
