The need for plastic corresponds with the annual rise in population. Meanwhile, waste that is improperly managed can negatively influence environment. Therefore, a more promising alternative recycling process needed to convert this into oil by cracking, and possibly assisted adding empty palm bunches. This study examines how modifications ratio of bunches Polypropylene (PP) percent liquid produ...

The fine-grained soil including the problematic ones can cause many difficulties in project accomplishment. Settlement and swelling are among the problems of the fine-grained soils. The present study compared the effects of the polypropylene waste plastic (PWP) and glass fiber reinforced polymer (GFRP) on geotechnical properties of the clayey soils for the subgrade design. To this end, the PWP ...

Plastic debris in the marine environment is widely documented, but the quantity of plastic entering the ocean from waste generated on land is unknown. By linking worldwide data on solid waste, population density, and economic status, we estimated the mass of land-based plastic waste entering the ocean. We calculate that 275 million metric tons (MT) of plastic waste was generated in 192 coastal ...

Separation of plastic from various types of waste streams represents one of major problematic process in energy recovery through different thermochemical processes. The sorting of plastics is a very essential step in different waste management technique. Manual sorting is suitable when plastic component are present in large amount but it is a labor intensive process. In automated sorting techni...

OBJECTIVE To compare the effect of storage on expressed colostrum kept at room and refrigeration temperature in 2 different types of containers (steel and plastic) at different time intervals (0 hours to 7 hours). DESIGN Prospective immunological study. SETTING Maternity ward. METHODS Colostrum was collected from 60 healthy lactating mothers and tested for total and differential cell coun...

Antibacterial property for the plastic products is very important due to their wide spread usage in many areas close to human health such as a child toy or a food package. There are some methods to make polymers antibacterial such as ionizing radiation but they can be still infected by micro organisms during usage of them. The best and easy way to obtain antibacterial polymers is melt mixing of...

In the domestic production of recycled plastics, it is difficult to separate olefin polymers such as polyethylene and polypropylene. Therefore, prerequisite for identifying cargo-solid waste properties plastics determine polymer composition. this paper, Fourier transform infrared spectroscopy was used detect polypropylene content in blends. Under 2%-8% content, an exponential relationship shown...

Identification and characterisation of microplastic (MP) is a necessary step to evaluate their concentrations, chemical composition and interactions with biota. MP ≥10μm diameter filtered from below the sea surface in the European and subtropical North Atlantic were simultaneously identified by visual microscopy and Raman micro-spectroscopy. Visually identified particles below 100μm had a signi...
