Advances in food packaging have delivered important benefits for food safety and for the durability of food (thus reducing food waste and the associated waste of resources and avoidable GHG emissions) and the sector is continuously innovating. However the packaging sector is also a user of nonrenewable resources and fossil fuels, and generates waste disposal issues.
This report by US non-profit Centre for International Environmental Law reviews research on the human health impacts of plastics throughout their lifecycle, including extraction of fossil fuels, refining and production, consumer use, waste management, fragmenting and microplastics and accumulation of plastics in food chains.
This feature in the Guardian explores the reasons for the rapid growth of the anti-plastic movement. It also describes historical lobbying campaigns that painted plastic packaging as being the responsibility of the consumer rather than manufacturers, and outlines some of the issues associated with recycling plastic (in comparison to recycling, say, glass or metals).
Utilities company Veolia and plastics charity RECOUP have together released the report “Plan for plastics”, which considers how the UK can improve plastic recycling. The report finds that 93% of people think plastic bottles should be made with recycled materials and are willing to pay 2.5 pence more, on average, for a recycled bottle (compared to a non-recycled bottle). Less than 5% of plastic film is currently recycled, compared to 59% of plastic bottles.
The UK’s Local Government Association (LGA) has called for industry to stop creating non-recyclable food packaging, saying that “Councils have done all they can,” to tackle the issue of plastic recycling. The LGA has found that only one-third of plastic packaging used by households can be recycled.
Disruptions to supplies of food-grade CO2 in Europe are causing shortages of carbonated drinks, meat and crumpets, and could threaten animal welfare. Gasworld explains that several European CO2 plants have prolonged their periods of maintenance downtime due to low CO2 prices (read more here).
A report by Friends of the Earth Europe finds that plastic food packaging is not a solution to growing levels of food waste in Europe, contrary to some claims that packaging can reduce food waste by extending the shelf life of foods. For example, using packaging to group food together in larger packs could encourage customers to buy more food than necessary. Another example is that green beans are often cut to fit into the packaging, causing losses of 30 to 40%.
Shoppers do not notice sustainability rating logos on packaging, according to a report by QuadPackaging and Package Insight. In the study, 60 participants had their eye movements tracked while “shopping” in a retail laboratory. The products they were presented with were fictional brands with logos claiming different levels of sustainability. The logos did not represent a real sustainability standard. While 40% of the participants said that sustainability affects their purchasing decisions, the eye-tracking technology showed that 92% of the participants did not notice the sustainability logos.
Scientists have unintentionally created a variant of a bacterial enzyme that is 20% better than the original at breaking down polyethylene terephthalate, commonly used to make plastic bottles. The researchers were investigating the properties of a bacterium that has naturally evolved to digest plastic.
UK charity WRAP has launched the UK Plastics Pact, a voluntary scheme which brings together businesses responsible for 80% of the plastic packaging on products sold in UK supermarkets. The pact aims to make 100% of plastic packaging reusable, recyclable or compostable by 2025, among other goals.
This paper examines some of the environmental trade-offs associated with using multilayered biodegradable packaging made of thermoplastic starch and polyhydroxyalkanoate.
A report (PDF link) tested bottled water in nine different countries and found that 242 out of 259 bottles contained small pieces of plastic. The report suggests that at least some of the plastic particles may be coming from the packaging or the bottling process.
You can view the full video recording of the panel talk “Reinventing the plastic bottle” which was hosted by the Hoffmann Centre for Sustainable Resource Economy at Chatham House. Speakers discussed problems created by single-use plastic bottles and some possible solutions.
Dutch shopping chain Ekoplaza has launched a plastic-free pop-up store in Amsterdam. Products sold include meat, rice, sauces, dairy, chocolate, cereals, fruit and vegetables. The aisle includes conventional packaging materials such as cardboard, glass and metal, but also introduces biodegradable replacements for plastic.
A new technology using a harmless laser beam can replace stickers on fresh food produce with a direct marking on the skin of a piece of fruit or vegetable. Named ‘Natural Branding’, the innovation could result in significant savings in sticker use as well as packaging. Nature and More, a Dutch organic food exporter, in collaboration with Swedish supermarket ICA is now using the branding on organic avocados and sweet potatoes.
In September 2016, France banned the use of non-biodegradable plastic cups and cutlery, as from 2020. The ban was proposed by Europe Écologie, Les Verts, France’s green party.
Old wine in new bottles: the winery Virginia Marie Lambrix has partnered with packaging specialists to create their new Truett Hurst PaperBoy wine bottle. The package replaces glass with recycled paper and all material inputs used in producing the bottle are included based on sustainability criteria. The outer shell is made of recycled corrugated waste and the thin plastic liner, screw cap closure, inks and other materials are all UV-based and do not contain volatile organic compounds.
An upcoming paper shows that Front-of-pack nutrition labels have little impact on consumer choice in a retail setting. The study: “Effects of nutrition label format and product assortment on the healthfulness of food choice,” examines the choices of 1000 German and Polish consumers.
