Abstract Amount of plastic use contribute significantly to the accumulation waste. The waste in concrete is one world’s partial solutions for dealing with Polypropylene granules are used as a replacement fine aggregate this study. purpose research examine physical and mechanical properties chosen base while considering potential polypropylene sand substitute mixture. Variables be investigated i...
The recycling of polypropylene recovered from waste discarded by a composting plant was investigated. recovery involved sorting step carried out means an optical infrared separator and subsequent washing treatment. This method processing allowed us to obtain that only slightly contaminated other polymeric inorganic materials. As many tens tons could be every year in this plant, convenient the e...
Although recycling is considered the core of a circular economy for returning materials to the supply chain, its procedures are poorly understood. Waste recycling is considered a big source of energy saving and a promoter of CO2 recovery. Besides that, it generates jobs and changes markets worldwide. The Brasilian National Policy on Solid Waste (PNRS) recognizes Waste Pickers as the major socia...
A two-stage reactor system consisting of co-pyrolysis biomass and plastic in the 1st stage catalytic upgrading (zeolite ZSM-5 catalyst) derived pyrolysis gases 2nd was used to investigate yield composition product bio-oil. Biomass waste wood plastics form high density polyethylene, low polypropylene, polystyrene polyethylene terephthalate were as feedstock. The addition with co-pyrolysis-cataly...
The occurrence of microplastics (MPs) in saltwater bodies is relatively well studied, but nothing is known about their presence in most of the commercial salts that are widely consumed by humans across the globe. Here, we extracted MP-like particles larger than 149 μm from 17 salt brands originating from 8 different countries followed by the identification of their polymer composition using mic...
Electrostatic separation of granular plastics mixtures has become a wellestablished technology, with industrial applications in the area of waste electric and electronic equipment (WEEE) recycling. The aim of this work is to validate the feasibility of selectively sorting of micronized waste plastics in a two-rotating-disks-type tribo-aero-electrostatic separator. The experiments are carried ou...
Conventional T-flasks with different sizes and layers are commonly used devices for static cell culture at laboratory scale. Due to their non-deformable structure and requirement of strict manufacture art, the rigid T-flask costs highly in production and transportation and, of course, produces more waste. In this study, we described a pentahedron shaped flexible flask made of a medical applicat...
Plastics debris in the marine environment, including resin pellets, fragments and microscopic plastic fragments, contain organic contaminants, including polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons, petroleum hydrocarbons, organochlorine pesticides (2,2'-bis(p-chlorophenyl)-1,1,1-trichloroethane, hexachlorinated hexanes), polybrominated diphenylethers, alkylphenols and bis...
