Sludge and digestate produced at TOYO BIOGAS POWER PLANT

Digestate is an organic fertilizer that has the fertilizing ingredients such as nitrogen, H3PO4(phosphoric acid) and K(Kalium) after anaerobic digesting the livestock manure and food residues.

It can be used instead of the chemical fertilizer and use it effectively for the wet-rice culture and vegetable farming.

For spreading the fertilizer, we hire people from local companies and seniors to contribute the job creation in the community as well as revitalizing the local economy.
