ABSTRACT

The waste cassava pulp of cassava starch processing p p p gplants is one of main causes of environment pollution problem, under ground water source and lakes ,rivers

hi h l i l twhich places near processing plants • The waste cassava pulp is yellow colour,has “died rat

ll” k t l tismell” as kept longtime. • Analyzing the waste pulp which has

0 4% l l+70-74% cenlul+20-30% protein + 3-5 % starch.

• The author has mechanical solution treats waste f fcassava pulp to supply material for the animal food

production and environment protection.

Introduce some treatment solutions of the other authors for reusing.

1.Putting the waster pulp into the under ground to make fertilizationg

2. Fermentation technology to make food for animalsanimals

3.Producing HCN acid… 4 All th t t t t h l i th fi t4.All there treatment technologies are the first

stage of research or limited in laboratories.5. Keeping waster pulp in big plastis bag to

make Biogas to burning
