[su-re.co venture] Benefits of bio-slurry

I am now checking the final report on sustainable agricultural production and consumption. The report is on three products: dairy, coffee and mango, and the common topic in all three is biogas and the by-product residues, called bioslurry, organic fertiliser. I am checking out the chapter on bio-slurry in the dairy report, so I will borrow that part. I actually took out the bioslurry yesterday (^^).




Dairy farms have animals and therefore produce large amounts of excrement and organic feed residues. If the waste is not managed correctly, not only does the area become damp and smelly, but it can also become habitable for harmful bacteria and lead to outbreaks of infectious diseases. It can also be the source of outbreaks of gastroenteritis-related diseases. These residues also lead to the emission of greenhouse gas - methane, which contributes to global warming. Thus, the design of cowsheds needs to consider the ease of washing cow waste, the flow of urine and proper drainage to ensure a dry and comfortable barn. The following should, therefore, be considered in the construction of cattle and piggeries.


  • The number of animals

  • The effects of direct sunlight and wind

  • The roof drainage and wash water drainage

  • Working environment

  • Collection of manure

  • Storage of feed and farm equipment






Animal manure can be a natural organic fertiliser, but it is better to collect it in a biogas digester and obtain biogas and bioslurry as a by-product than to use it directly. The decomposed dung, as a bioslurry, provides nitrogen and other nutrients suitable for agriculture.


Benefits of bio-slurry

  • Reduces greenhouse gases and emissions by reducing the use of synthetic fertilisers.

  • Improves feed and agricultural productivity.

  • Improves the quality of nutrients and food safety on the farm

  • Promotes a circular economy


Other than the funding for the installation, there will be no problems. If the cattle and piglets are designed and built to ensure the manure flow into the biogas digester, there is no need for the digester to be filled.
