The development of the marine aquaculture industry has led to the generation of significant amounts of fish wastes. Marine farm wastes exert adverse effects on the surrounding area of the cages. On the other hand, wastes of fish and other aquatic animals are regarded as major sources of valuable natural bioactive compounds, including enzymes, proteins, bioactive peptides, oil, amino acids, coll...

Livestock manure and organic agriculture wastes are an environmental challenge because they contribute to climate change by emitting greenhouse gases. Converting these biogas bioenergy is a sustainable solution. Farmers, investors, governmental departments involved in developing on-farm projects need informed decision-making process fund such projects. Thus, estimating the required initial inve...

Anaerobic digestion is a process which breaks down organic matter in simpler chemicals components without oxygen. This process can be very useful to treat arising organic waste such as:-sewage sludge-organic farm wastes-municipal solid wastes-green/botanical wastes-organic industrial and commercial wastes Before being digested, the feedstock has to und ergo pre-treatment. There are various type...

Leather industry, one of the polluting industries because of generation of huge amount of liquid and solid wastes, also emits obnoxious smell because of degradation of proteinous material of skin and generation of gases such as NH3, H2S and CO2. Solid wastes are raw trimmings, fleshings, chrome shavings, buffing dusts and keratin wastes. Accumulation of these wastes lead to sludge problem and c...

Medical wastes include all infectious waste, hazardous (including low-level radioactive) wastes, and any other wastes that are generated from all types of health care institutions, including hospitals, clinics, doctor (including dental and veterinary) offices, and medical laboratories (42). 1 The main focus of concern has been on the portion of medical wastes that are defined as infectious, and...

The technique of the processor farm has become very widely used for paral lelising applications often being mentioned without reference to any source The goal of this work has been to put together a complete and rigorous un derstanding of what the technique can be used for and what is needed in order to arrive at an e ciently farmed application This paper consists of these two parts We have sho...

A new hybrid system of biogas production was developed for treating the piggery wastes at Kasetsart University Animal Research Farm. The system is a combination of a settler, a low rate anaerobic digester (generally known as biogas plant) and a newly developed aerobic digester (namely bio-contact aeration system). The settle separates piggery waste water into two parts : a low-volume solid port...
