aerobic fermentation (FVSSAF) system (Scenario A) and the bedding recovery unit (BRU) system (Scenario B). It covered the whole process from the transportation of cow dung to the treatment area where recycled cow dung into a usable cow mattress. Furthermore, the advantages and disadvantages of the two kinds of bedding material

Cowlogy Institute. A top manufacturer of sustainable and eco-friendly bricks. and logs made up of cow dung. Our company was established. with the intention of providing a modern and sustainable. alternative to traditional brick-making techniques, which. frequently contribute to environmental damage and the depletion of natural resources.

A cow produces much waste per year. While, if there is a cattle farm, how much waste will be produced? Cow dung is good materials for making organic fertilizers. However, it is a waste if you do not to get rid of it. Cow dung fertilizer machine is helpful. With cow dung machine, you can turn the waste into treasurable organic fertilizers.

for 48 h. Cow dung substrate was processed as described previously (Vijayaraghavan et al. 2012). Equal amount of cuttle fish and cow dung waste were mixed and used as the substrate. 5 g of substrate (2.5 g cuttle fish waste ?2.5 g cow dung) was taken in 100 ml Erlenmeyer flasks and the pH of the solid substrate medium was adjusted to 8.0 by the
