Phase-out Of Lightweight Plastic Bags
A plastic bag ban is a law that restricts the use of lightweight plastic bags at retail establishments. In the early 21st century, there has been a global trend towards the phase-out of lightweight plastic bags. Single-use plastic shopping bags, commonly made from low-density polyethylene (LDPE) plastic, have traditionally been given for free to customers by stores when purchasing goods: the bags have long been considered a convenient, cheap, and hygienic way of transporting items. Problems associated with plastic bags include use of non-renewable resources (such as crude oil, gas and coal), difficulties during disposal, and environmental impacts. Concurrently with the reduction in lightweight plastic bags, shops have introduced reusable shopping bags. Various governments have banned the sale of lightweight bags, charge customers for lightweight bags, or generate taxes from the stores that sell them. The Bangladesh government was the first to do so in 2002, imposing a total ban on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic Bags
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. It is a common form of packaging. Most plastic bags are heat sealed at the seams, while some are bonded with adhesives or are stitched. Many countries are introducing legislation to phase-out lightweight plastic bags, because plastic never fully breaks down, causing everlasting pollution of plastics and environmental impacts. Every year, about 1 to 5 trillion plastic bags are used and discarded around the world. From point of sale to destination, plastic bags have a lifetime of 12 minutes. Approximately 320 bags per capita were used in 2014 in the United States of America. Package Several design options and features are available. Some bags have gussets to allow a higher volume of contents, special stand-up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethylene
Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula or . It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. It is the simplest alkene (a hydrocarbon with carbon-carbon double bonds). Ethylene is widely used in the chemical industry, and its worldwide production (over 150 million tonnes in 2016) exceeds that of any other organic compound. Much of this production goes toward polyethylene, a widely used plastic containing polymer chains of ethylene units in various chain lengths. Ethylene is also an important natural plant hormone and is used in agriculture to force the ripening of fruits. The hydrate of ethylene is ethanol. Structure and properties This hydrocarbon has four hydrogen atoms bound to a pair of carbon atoms that are connected by a double bond. All six atoms that comprise ethylene are coplanar. The H-C-H angle is 117.4°, close to the 120° for ideal sp² hybridized carbon. The molecule is also relatively weak: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Norfolk Island
Norfolk Island (, ; Norfuk: ''Norf'k Ailen'') is an external territory of Australia located in the Pacific Ocean between New Zealand and New Caledonia, directly east of Australia's Evans Head and about from Lord Howe Island. Together with the neighbouring Phillip Island and Nepean Island, the three islands collectively form the Territory of Norfolk Island. At the 2021 census, it had inhabitants living on a total area of about . Its capital is Kingston. The first known settlers in Norfolk Island were East Polynesians but they had already departed when Great Britain settled it as part of its 1788 settlement of Australia. The island served as a convict penal settlement from 6 March 1788 until 5 May 1855, except for an 11-year hiatus between 15 February 1814 and 6 June 1825, when it lay abandoned. On 8 June 1856, permanent civilian residence on the island began when descendants of the ''Bounty'' mutineers were relocated from Pitcairn Island. In 1914 the UK handed No ...

United Nations Regional Group
The United Nations Regional Groups are the geopolitical regional groups of member states of the United Nations. Originally, the UN member states were unofficially organized into five groups as an informal means of sharing the distribution of posts for General Assembly committees. Now this grouping has taken on a much more expansive and official role. Many UN bodies are allocated on the basis of geographical representation. Top leadership positions, including Secretary-General and President of the General Assembly, are rotated among the regional groups. The groups also coordinate substantive policy and form common fronts for negotiations and bloc voting. History League of Nations The precedent of the geographic distribution of seats was set by the United Nations' predecessor, the League of Nations. Under the League's system, a Nominations Committee was created in order to create election slates for distribution of seats in the Council of the League. This proved a difficult ta ...

Plastic Bag Legislation
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1,1 ...

Marine Debris
Marine debris, also known as marine litter, is human-created waste that has deliberately or accidentally been released in a sea or ocean. Floating oceanic debris tends to accumulate at the center of gyres and on coastlines, frequently washing aground, when it is known as ''beach litter'' or tidewrack. Deliberate disposal of wastes at sea is called ''ocean dumping''. Naturally occurring debris, such as driftwood and drift seeds, are also present. With the increasing use of plastic, human influence has become an issue as many types of (petrochemical) plastics do not biodegrade quickly, as would natural or organic materials. The largest single type of plastic pollution (~10 %) and majority of large plastic in the oceans is discarded and lost nets from the fishing industry. Waterborne plastic poses a serious threat to fish, seabirds, marine reptiles, and marine mammals, as well as to boats and coasts. Dumping, container spillages, litter washed into storm drains and waterways ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grocery Bag Comparisons For Greenhouse Gas Emissions, OWID
A grocery store ( AE), grocery shop ( BE) or simply grocery is a store that primarily retails a general range of food products, which may be fresh or packaged. In everyday U.S. usage, however, "grocery store" is a synonym for supermarket, and is not used to refer to other types of stores that sell groceries. In the UK, shops that sell food are distinguished as grocers or grocery shops (though in everyday use, people usually use either the term "supermarket" or a "corner shop" or "convenience shop"). Larger types of stores that sell groceries, such as supermarkets and hypermarkets, usually stock significant amounts of non-food products, such as clothing and household items. Small grocery stores that sell mainly fruit and vegetables are known as greengrocers (Britain) or produce markets (U.S.), and small grocery stores that predominantly sell prepared food, such as candy and snacks, are known as convenience shops or delicatessens.

Polymer Degradation
Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition. Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling. The rate of this degradation varies significantly; biodegradation can take decades, whereas some industrial processes can completely decompose a polymer in hours. Technologies have been developed to both inhibit or promote degradation. For instance, polymer stabilizers ensure plastic items are produced with the desired properties, extend their useful lifespans, and facilitate their recycling. Conversely, biodegradable additives accelerate the degradation of plastic waste by improving its biodegradability. Some forms of plastic recycling can involve the complete degradation of a polymer back into monomers or other chemicals. In general, the ef ...
