Production of methane gas from organic fraction municipal solid waste (OFMSW) via anaerobic process: application methodology for the Malaysian condition
Solid waste management in Malaysia is confronted with many problems, including low collection coverage, irregular collection services, inadequate equipment used for waste collection, crude open dumping and burning without air and water pollution control systems, inadequate legal provisions and resource constraints. These problems have various effects on the development of the solid waste ...

Comparative assessment of anaerobic digestion of municipal solid waste at mesophilic and thermophilic temperatures
Anaerobic digestion is an environmentally sound treatment option for the organic fraction of municipal solid waste (OFMSW) and simultaneously producing methane gas which is a source of renewable energy. The COD reduction of the substrate was 72% for the mesophilic condition and 72.3% for the thermophilic condition. 1200 cm³ of methane was produced in the mesophilic condition and 1260 cm³ in the ...

A fuzzy rule–based approach for modelling effects of bench–scale microwave pre–treatment on solubilisation and anaerobic digestion of secondary sludge
Fuzzy rule–based models were proposed in order to predict the effect of microwave pretreatment on the waste activated sludge (WAS) solubility and anaerobic digestibility or biogas production. The developed models were trained and validated using the experimental data from two separate multilevel factorial designs, containing 24 solubilisation and 54 biogas production runs from batch mesophilic ...

Going further with food: The rise of channelling food waste for biogas production
Almost 50% of the total amount of food thrown away in the UK comes from our homes, representing over seven million tonnes of food and drink wasted from British households annually. Wasting this food costs the average household £470 a year. In fact, if we all stop wasting food that could have been eaten, the benefit to the planet would be the equivalent of taking 1 in 4 cars off the road ...

How Safer Biogas Tanks Can Save You Thousands of Dollars
As a type of biofuel that not only eliminates waste but also produces a valuable energy source, biogas production has increased in recent years. According to the US Energy Information Administration, biogas contributed to approximately 11.5 billion kilowatt-hours of electricity back in 2017. However, biogas can be only be produced in an anaerobic environment without oxygen. This is a very ...

Wastewater and Waste-to-Energy for Candied Fruit Manufacturer - Case study
An anaerobic digester allows an Italian food producer to turn waste into more than enough energy to power the plant A candied fruit manufacturer sought to double production and simultaneously reduce overall costs while increasing its wastewater treatment capabilities. Fluence provided a custom solution: Wastewater effluents from fruit, candies, and jam are pretreated, then treated in an ...

How Many Anaerobic Digesters Are in the US?
There is enormous potential to increase the extraction of energy from farm waste Agricultural waste is one of the largest sources of methane emitted into the atmosphere from human activities. Methane is a potent greenhouse gas but it’s also highly combustible, making it a valuable source of renewable energy when captured. Anaerobic digesters can convert farm waste into methane-rich ...

Using Granular Sludge to Improve Digester Performance
Granular sludge technology compounds already impressive benefits of anaerobic digestion Anaerobic digestion is a robust process that transforms organic waste into valuable biogas for energy, as well as nourishing biosolids for agriculture. Applied in wastewater treatment, it also has the advantages of: Purifying even challenging, high-organic-load wastewater Lowering utility bills and ...

Inflation Reduction Act to Boost Biogas Projects in the United States
With an underdeveloped waste-to-energy market, new legislation promotes greater adoption of anaerobic digestion On August 16, United States President Biden signed the $750 billion Inflation Reduction Act (IRA) into law and biogas industry groups immediately hailed its hefty incentives for anaerobic digestion, a technology that recovers energy from waste in the form of ...

Bio hydrogen production from kitchen waste
The hydrogen producing organisms such as Escherichia coli (E.Coli), Enterobacter cloacae, Hafnia alvei, Citrobacter freundii, Serratia marcescens and Clostridium acetobutylicum strains were isolated from the sludge of biogas plant. The hydrogen producing efficiency of isolated organisms from kitchen waste were examined under anaerobic conditions. Lab scale studies were conducted under controlled ...

Quantifying the impacts of co-digesiton of waste streams with sewage sludge
In order to slow down the impending impacts of global climate change due to consumption of fossil fuels, governments are looking at ways to develop and incentivise alternative renewable energy sources. Subsequently, the UK has imposed renewable energy targets of 15% of all energy consumption by the year 2020, but admit that – in order to meet carbon dioxide reductions of 20% by 2020 – renewable ...

Energy self-sufficient sewage wastewater treatment plants: is optimized anaerobic sludge digestion the key?
The anaerobic digestion of primary and waste activated sludge generates biogas that can be converted into energy to power the operation of a sewage wastewater treatment plant (WWTP). But can the biogas generated by anaerobic sludge digestion ever completely satisfy the electricity requirements of a WWTP with ‘standard’ energy consumption (i.e. industrial pollution not treated, no ...
