In the plastics industry, the diffusion of ,supercritical, CO 2 in polymers is accompanied by a swelling of these materials and a change for their physico-chemical ,properties,. ,Supercritical, CO 2 is a good plasticizing agent in particular because it reduces the glass transition temperature. The resulting polymer ,properties, are usually improved (resistance, thermal stability, purity).

Abstract. The petroleum ,sludge, composting in a bioreactor with green wastes was made in interest to assess the organic matter biotransformation, the total petroleum hydrocarbons biodegradation and the maturity of the final product. During the composting process the C/N and NH 4+ /NO 3− ratios decreased to reach values of maturity for the second ...
