Shale is characterized by its tendency to split into thin layers less than one centimeter in thickness. This property is called fissility. [1] Shale is the most common sedimentary rock. [2] The term shale is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the narrower sense of clay-rich fissile mudrock. [3]
A plastic bag, poly bag, or pouch is a type of container made of thin, flexible, plastic film, nonwoven fabric, or plastic textile. Plastic bags are used for containing and transporting goods such as foods, produce, powders , ice, magazines , chemicals , and waste .
Since 2008, Japan has increased plastic recycling, but still has a large amount of plastic wrapping which goes to waste. Plastic recycling in Japan is a potential US$90 billion market. [26] It is possible to rapidly convert polyethylene to hydrogen and graphene by heating. The energy needed is much less than for producing hydrogen by electrolysis.
Some bags have handles that may be tied or holes through which the neck of the bag can be pulled. Most commonly, the plastic used to make bin bags is the rather soft and flexible LDPE (low-density polyethylene) or, for strength, LLDPE (linear low-density polyethylene) or HDPE (high-density polyethylene) are sometimes used.
Such sources of secondary microplastics include water and soda bottles, fishing nets, plastic bags, microwave containers, tea bags and tire wear. [ 69 ] [ 68 ] [ 70 ] [ 71 ] Both types are recognized to persist in the environment at high levels, particularly in aquatic and marine ecosystems , where they cause water pollution . [ 72 ]
Plastic shopping bags are in most cases not accepted by standard curbside recycling programs; though their composition is often identical to other accepted plastics, they pose problems for the single-stream recycling process, as most of the sorting equipment is designed for rigid plastics such as bottles, [34] so plastic bags often end up ...
