Disposable coffee capsules as a source of recycled polypropylene

BioCap Disposable Filter Capsules

Necessity of prerinsing disposable polypropylene pipet tips.

Piston-actuated microliter pipeta are frequently used to sample and dispense known volumes. These pipets maintain high accuracy and precision when used for rapid serial applications and are ideally suited for radiochemical experiments, because test solutions come in contact only with the disposable polypropylene tips. Their accuracy is affected by temperature differences between the pipet and t...

Recycled Plastics as an Energy Source

The order is based on the economic value of the recycled product. The highest priority is based on using the plastic for its original specifications, which retains the energy and effort needed to produce the plastic and gives a high sales price. However, the recycled material would compete with virgin resin, and would have to have high purity. The lowest priority converts the material to energy...

Characterization of Laccase-Treated Kenaf Fibre Reinforced Recycled Polypropylene Composites

Raw and laccase-treated kenaf fibre (KF) were used individually to reinforce recycled polypropylene (RPP) using extrusion and injection moulding. Laccase was used to modify the surface of the fibre to improve the compatibility between fibre and matrix. Enzyme concentration and soaking time were considered as the treatment parameters. Maleic anhydride grafted polypropylene (MAPP) was used with a...
