The biochemical methane potential (BMP) of different Estonian substrates as alternative sources for biogas production was studied. For this purpose, the BMP test was carried out in batch mode at mesophilic temperature (36°C). Substrates were divided into 2 groups: agricultural substrates (silage, hay, cattle and pig slurry) and food industry residues (milk, brewery and cereal industry residues)...

There is a great worldwide demand for citric acid consumption due to its low toxicity when compared with other acidulants used mainly in the pharmaceutical and food industries. Other applications of citric acid can be found in detergents and cleaning products, cosmetics and toiletries, and other. Global production has now reached 1.4 million tonnes and there is annual growth of 3.5–4.0 % in dem...

Oil cakes have been in use for feed applications to poultry, fish and swine industry. Being rich in protein, some of these have also been considered ideal for food supplementation. However, with increasing emphasis on cost reduction of industrial processes and value addition to agro-industrial residues, oil cakes could be ideal source of proteinaceous nutrients and as support matrix for various...

In recent years, there has been a significant accumulation of waste in the environment, and it is expected that this may increase years to come. Waste disposal massive effects on environment can cause serious environmental problems. Thus, development treatment system major importance. Agro-industrial wastewater residues are mainly rich organic substances, lignocellulose, hemicellulose, lignin, ...

Synthetic pesticides have a number of ill effects on soil, water, human health, wildlife and ecological balance. These ill effects have led to the use of microbial insecticides against insect pests of order Lepidoptera, Coleoptera, Diptera and Hemiptera. Bacillus thuringiensis is a gram-positive endospore forming bacterium that produces a parasporal crystal protein inclusion during sporulation ...

The bio-wastes pyrolysis is a waste to energy strategy that converts into valuable products (bio-char, bio-oil) with wide use in the agri-food sector. However, limited efforts are paid investigation of its environmental sustainability: this context, study contributes need towards assessment range impacts for process different types under operating conditions. estimates potential related bio-cha...

The presence of heavy metals in aqueous media represents a severe threat to ecosystems because they are non-biodegradable, toxic, and carcinogenic. In the present work, utilization agro-industrial residues from obtaining plantain starch for removing Ni (II) was studied, establishing effect temperature, adsorption dose, initial concentration. kinetics, equilibrium, thermodynamic parameters that ...
