A METHOD OF MAKING STRUCTURAL MEMBERS USING WASTE AND RECYCLED PLASTICS |
摘要 |
<p>A composite formulation consisting of agglomerated industrial/residential sewer sludge and recycled high density polyethylene (HDPE) and/or polypropylene (PP) materials. The recycled plastic materials act as a binder for the pozzolan industrial/residential sewer sludge. The composite formulation can be produced in a batching process wherein the sieved dried sewer sludge and the recycled plastic in appropriate small cut pieces is fed into a large plastic extruder, heated and extruded into specific structures. The formulation can also be compounded using a compression mold wherein sieved dry sewer sludge are added to heated chopped recycled plastics and heat mixed to produce pellets or directed into a compression mold to create a structural member of predetermined shape.</p> |
