ISO provides guidance for the development of standards and specifications covering plastics waste recovery, including recycling. The standard establishes the different options for the recovery of plastics waste arising from pre-consumer and post-consumer sources. It also establishes the quality requirements that should be considered in all steps of the recovery process, and provides general recommendations for inclusion in material standards, test standards and product specifications. Consequently, the process stages, requirements, recommendations and terminology presented in the standard are intended to be of general applicability. Proof returned by secretariat 60 Publication

Plastic recycling refers to the process of recovering waste or scrap plastic and reprocessing the materials into functional and useful products. This activity is known as the plastic recycling process. This approach helps to conserve resources and diverts plastics from landfills or unintended destinations such as oceans. Plastics are durable, lightweight and inexpensive materials.
Plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful products. Materials recovery facilities are responsible for sorting and processing plastics. As of , due to limitations in their economic viability, these facilities have struggled to make a meaningful contribution to the plastic supply chain. However, the industry has lobbied for the expansion of recycling while these companies have continued to increase the amount of virgin plastic being produced.
Extracting value from plastics waste can be achieved through recycling and energy recovery, helping to save money and meet sustainability objectives. Mechanical recycling of plastics refers to the processing of plastics waste into secondary raw material or products without significantly changing the chemical structure of the material. In principle, all types of thermoplastics can be mechanically recycled with little or no quality impairment. Waste streams that can easily provide clean plastic of a single type in large quantities are ideal for mechanical recycling and represent a win-win situation from an environmental and economic perspective: environmental benefits from substituting virgin material generally exceed the environmental burden from collection, sorting, transport and recycling operations, while the costs of such operations can be outweighed by potential revenues from selling recyclates on the market. Plastics and plastics-containing waste that cannot be sustainably mechanically recycled to the required standard from an economic and environmental perspective provides a valuable resource for other recovery solutions such as feedstock recycling and energy recovery to maximise the recovery of its embedded energy and resources. PlasticsEurope is committed to helping develop quality-focused recycling processes for plastics waste and to promote such solutions in all European countries.
In the plastic bottle was introduced nationwide. In the thirteen years since that historic and some say environmentally devastating occasion, the consumer increasingly has embraced plastic packaging. Each American uses about pounds of plastic per year, according to Earthworks Group, and about 60 pounds of it is discarded within minutes or seconds after opening. The plastic bottle is king.
Встретимся в Стоун-Мэнор. Она кивнула, и из ее глаз потекли слезы. - Договорились. - Агент Смит! - позвал Фонтейн. Из-за спины Беккера появилось лицо Смита. - Слушаю, сэр. - Мне кажется, мистер Беккер опаздывает на свидание.
Интересно, почему Стратмор его до сих пор не отключил. Ему понадобилось всего несколько мгновений, чтобы принять решение. Фонтейн схватил со стола заседаний трубку внутреннего телефона и набрал номер шифровалки.
Сьюзан, - умоляюще произнес Стратмор, не выпуская ее из рук. - Я все объясню. Она попыталась высвободиться. Коммандер не отпускал .
