deadly wastes can be encapsulated in glass, cement, or ceramics and then put in secure storage sites

used to convert hazardous chemicals to harmless or less harmful chemicals through chemical reactions

for treatment of hazardous waste to be the wave of the future

bacteria and enzymes help to destroy toxic or hazardous substances or convert them to harmless compounds

involves using natural or genetically engineered plants to absorb, filter, and remove contaminants from polluted soil and water
