ABSTRACT
PT Kertas Leces, a paper factory using bagasse as r a w
material,
faces many problems i n waste management, espec i a l l y those o f huqe volume and v a r i e t y i n solld wastes.
The s o l i d wastes discharged consist o f sludge, lime m u d ,
p i t h , and biosludge. A s e r i e s o f experiments has been
conducted t o determine possible a l t e r n a t i v e s f o r agricult u r e uses o f those wastes based on i t s respective propert i e s . The experiments included ( 1 ) composting o f sludge,
