Organic waste may degrade anaerobically in nature as well as in engineered systems. The latter is called anaerobic digestion or biogasification. Anaerobic digestion produces two main outputs: An energy-rich gas called biogas and an effluent. The effluent, which may be a solid as well as liquid with very little dry matter may also be called a digest ...

Valorization of anaerobic digestion digestate: A prospect review
Bioresource Technology, 2021Anaerobic digestion is recognized as promising technology for bioenergy production from biowaste, with huge quantity of digestate being produced as the residual waste. The digestate contains substantial amounts of organic and inorganic matters that be considered highly risky contaminants to the receiving environments if not properly treated, but also ...

Anaerobic Digestion: Factors Affecting Anaerobic Digestion Process
2017Anaerobic digestion (AD) is a biological decomposition process that occurs in the absence of oxygen. The decomposition of organic matter is a multi-step process of series and parallel reactions namely hydrolysis, acidogenesis, acetogenesis and methanogene.

Perspectives for Anaerobic Digestion
2003The modern society generates large amounts of waste that represent a tremendous threat to the environment and human and animal health. To prevent and control this, a range of different waste treatment and disposal methods are used. The choice of method must always be based on maximum safety, minimum environmental impact and, as far as possible, on ...

Anaerobic digestion of submerged macrophytes: Chemical composition and anaerobic digestibility
Ecological Engineering, 2014Abstract Aquatic weeds including submerged macrophyte have been excessively propagated and causing environmental issues in freshwater environment of many countries, and the sustainable treatments have been investigated. In the present study, five submerged macrophyte species dominant in Lake Biwa, Japan, Ceratophyllum demersum, Egeria densa, Elodea ...

Modeling of Anaerobic Digestion of Sludge
Critical Reviews in Environmental Science and Technology, 2009Anaerobic treatments have been successfully employed for more than one hundred years to stabilize sewage sludge. The main aim of sludge anaerobic digestion is the degradation and destruction of organic matter, with consequent sludge stabilization and pathogen reduction.

Anaerobic digestion of extruded OFMSW
Bioresource Technology, 2012Organic fraction of municipal solid waste (OFMSW) was used to feed two pilot plants of 1000 l working in anaerobic conditions. The OFMSW had previously been treated using a system of extrusion which, due to exerted pressure, separates the undesired fractions of waste from organic waste and reduces the organic fraction in a kind of homogeneous jam ...

Anaerobic digestion of sewage sludge in an anaerobic fixed bed digester
Biomass and Bioenergy, 1995The anaerobic digestion of sewage sludge in conventional reactors requires a hydraulic retention time of around 20 days. By using a fixed bed reactor the hydraulic retention time was reduced to 3–7 days. Recirculation increased the removal of organic matter in this system.

Applications of the Anaerobic Digestion Process
2003At the start of the new millennium waste management has become a political priority in many countries. One of the main problems today is to cope with an increasing amount of primary waste in an environmentally acceptable way. Biowastes, i.e., municipal, agricultural or industrial organic waste, as well as contaminated soils etc., have traditionally ...
