In Northwest China, is more serious than that in North China and Southwest China. Because of difference of tillage and appli-cation ways, there are great differences on the area and shape of the plastic film piece left in soil. The main types of shapes are flaky, crispat-ural cylindric ...
of plastic waste into its different types. The process is rapid, requires small quantities of dye additive and by a combined measurement of fluorescence wavelength and lifetime allows differentiation of a greater number of marked plastic types than prior art. 展开 ...
“Take urgent action to combatclimate changeand its impacts”;Walker, 2021). While certain countries have addressed the impact of plastic pollution through the implementation of policies and long-term monitoring programs, many are broad and not species-specific enough to make a direct impact (Linne...
Plastic, polymeric material that has the capability of being molded or shaped. This property of plasticity, often found in combination with other special properties such as low density, low electrical conductivity, transparency, and toughness, allows pla
and park benches. Owing to itsheterogeneouscomposition, plastic lumber is inherently weaker than the original polymers. Other recycling processes that make use of mixed plastics are pyrolysis, which converts the solids into a petroleum-like substance, and direct incineration, which can provide energy...
Different plastic types and shapes will fragment at different rates in the environment, with thinner plastic pieces expected to degrade relatively faster (Eubeler et al. 2009; Rhodes 2018). In general, the defragmentation rate for plastics is below 1–3% weight per year in sediment or water, ...
