Polyethylene (PE), paper pulp and bamboo (chopsticks) were adopted to represent three major components in MSW in the experiments.
Three layers are identified, namely, polyethylene, a paper and talc layer (with two distinct cellulose forms), and a poly-styrene co-polymer composite containing anatase and calcite.
These containers are made from a variety of materials such as paper, polyethylene film, sisal, hessian or woven polyethylene and are relatively cheap but give little protection to the crop against handling and transport damage.
In this paper, polyethylene terephthalate (PET) films are modified by a dielectric barrier discharge (DBD) in a helium/air mixture at medium (6.6 kPa) and atmospheric pressure.
Other nominees included the environmental artist Karla Black, who used everything from swags of painted polyethylene and sugar paper to topsoil and bath products in an exploration of the physical realities of colour and form; George Shaw, a painter who portrayed the rundown Coventry (Eng).
In the city of Johannesburg for example, informal waste pickers have now become part of the waste management landscape and are involved in municipal waste collection, sorting and recycling of economically viable recyclable materials such as paper, Polyethylene Terephthalate (PET) and ferrous metals.
This is because most of flexible substrates (such as paper, polyethylene terephthalate (PET), and polyvinyl chloride (PVC)) cannot resist to this high sintering temperature [34 36].
Aliquots (20 μl) of the incubation solution were spotted onto polyethylene-backed absorbent paper (BenchGuard™, Lennox, Dublin, Ireland), allowed to dry, scanned, and digitized in the phosphorimager parallel with the tissue scans.
The surface area of each region was determined by tracing the polyethylene film regions onto paper of known weight per area and weighing the paper.
The design of these cups – lined with polyethylene to prevent the paper going soggy – makes recycling difficult and costly; the cups cannot be recycled with other paper waste as they require specialist processing to separate the plastic lining.
