Analysis of land application as a method of disposal for distillery effluent

Distillery companies in the Philippines produce high-strength wastewater that pollutes the waterways of the country. The implementation of a comprehensive water pollution control programme of these companies in order to comply with the regulations of the government through the Department of Environment and Natural Resources (DENR) requires a large investment. Non-compliance, on the other hand, requires a huge amount of penalties as mandated by the Philippine Clean Water Act of 2002, which can lead to economic loss. Putting up a state-of-the-art wastewater treatment to follow regulations is not economically viable. This paper aims to present an alternative solution in the management of the generated wastewater of the distillery industry that has not been considered previously. Wastewater or effluent from distillery companies can be used in agricultural applications. Researches have shown that distillery effluent can be a good source of nutrients necessary for plant growth and can be a viable fertiliser in sugarcane fields. Results showed that this effluent in combination with commercial nitrogen fertiliser at regulated rates increases the sugarcane yield.
