ABSTRACT
Brewery waste water sludge (BWS) is produced as the result of aerobic biological treatment of brewery effluent. Analysis of this waste material revealed that it contained valuable nutrients for plant growth with high water retention. Germination and plant growth trials were carried out with chili and pumpkin. The potential of applying sun dried brewery waste water sludge and admixing with two different types of compost were evaluated and outlined in this paper.
Key words:
Brewery waste water sludge, compost, germination water retention.
