Waste

It is estimated that 3.4 billion tonnes of plastic packaging were created between 1950 and 2017. Most plastic packaging is disposed of within a relatively short time. Discarded packaging accounts for 46% (158 million tonnes) of total annual plastic waste generation. Most plastic packaging waste is estimated to come from household waste. According to a 2010 survey by the Waste and Resources Action Programme (WRAP), 73% of all plastic packaging waste in the United Kingdom came from households. Waste plastic packaging makes up a considerable portion of collected aquatic litter (15.9% in the oceans and 74.5% in rivers). In a 2019 report,

Alternatives

Alternatives such as cotton bags, cardboard boxes and aluminum cans often have larger ecological footprints because these use up more energy and water to manufacture and transport than their plastic equivalents. In addition, very few countries have facilities for recycling materials that are deemed to be less environmentally harmful than plastic. In most cases, this allegedly safe packaging gets in the natural landscape in the form of waste.

Trade groups

In the U.S., the industry is represented by the Society of the Plastics Industry, Closure & Container Manufacturers Association, Flexible Packaging Association, and others.

Global market

Today packaging is the largest use of plastic resins, accounting for 36% (158 million tonnes) of the world's total plastic production by mass. Plastic packaging is used in the commercial, retail, household, tourism and agricultural sectors. Consumption rates vary among and within countries, with developing countries generally less reliant on packaging. In China annual plastic packaging consumption is approximately 14 kg/capita; in Europe the rate is much higher, averaging 174 kg/capita. Asia Pacific dominated the global plastic packaging market in 2016. In second place comes North America. The pharmaceutical and food and beverage industries contributed the most to the use of plastic packaging products. During 2016, Asia Pacific accounted for more than 30 percent of the shares of the total volume consumption in this market. The Ocean Conservancy reported that China, Indonesia, Philippines, Thailand, and Vietnam dump more plastic in the sea than all other countries combined.
