Biodegradable Label Less Eco-Friendly Than It Promises

South Africans buying products with "biodegradable" plastic packaging are often duped by companies eager to profit from the current trend towards environmentally-conscious consumerism. While the plastics do break up into small pieces, they remain toxic and potentially dangerous to human health.

In an attempt to reduce pollution and the amount of waste going into limited landfill space, the country has started to buy into a newly developed form of plastic that rapidly degrades, known as oxo-biodegradable plastic. However, these plastics have come under fire by environmentalists because, contrary to how they are marketed, they are not truly biodegradable.

Lack of environmental regulation means that labelling can be misleading and consumers don’t necessarily get what they are promised. South Africa does not have a certification system in place which distinguishes between degradable and biodegradable plastics.

Oxo-biodegradable plastic is, like other plastics, petroleum-based, with an added chemical which breaks up the product into tiny little pieces. As a result, these plastics don't take up space in landfills but they produce toxic dust that pollutes the environment and is known to be detrimental to human health.

Last year, British manufacturer Symphony Environmental Technologies clinched a deal to supply plastic packaging to Albany Bakeries, a subsidiary of South African food giant Tiger Brands. It claims its packaging contains an added chemical compound that causes the plastic to degrade in less than six months, leaving behind no fragments or harmful residues.

However, environmental experts say this is not good enough to be rated biodegradable. "To be beneficial to the environment, a polymer [plastic] should disappear completely. In biodegradation this means a natural conversion to CO2 and water," explained Bruno de Wilde, lab manager at Organic Waste Systems (OWS), a Belgium consulting company that tests and certifies the biodegradability of consumer products and packaging.

Not certified

Another problem with oxo-biodegradable plastics is that they can only be safely and successfully recycled if they are captured into the recycling stream within a few days of use.

"In waste collection you don’t know how old plastics are, so it is likely that in the mechanical sorting process, oxo-biodegradable plastics could end up in the manufacture of other products and continue to degrade," said David Hughes, executive director of the Plastics Federation of South Africa who has convinced industry heavyweights like Coca-Cola and Woolworths to steer clear of oxo-biodegradable plastic.

"Recycling companies won’t want to take products made from oxo-biodegradable plastics. This will disrupt the recycling industry which is creating jobs in South Africa," he added.

Albany Bakeries is not the only company in South Africa trying to appeal to environmentally conscious consumers by marketing its packaging as biodegradable.

Astrapak, one of the biggest producers of plastic packaging in the country, manufactures a plastic degradable garbage bag made from petroleum-based granules into which it will degrade after usage.

But environmental experts like de Wilde, warn that the minuscule plastic fragments the bag degrades into may enter the food chain and pose health risks. Most plastics contain harmful chemicals, such as sulphur and ethylene oxides, which can cause respiratory and reproductive problems.

To date, oxo-biodegradable plastics have not met the internationally-accepted standards for compostable and biodegradable packaging which ensures that a product breaks down completely in a landfill or an industrial compost heap. To be certified as biodegradable, a product must be fully tested and approved by internationally-recognised bodies, such as the Institute for Standards Research (ISR) and the International Standards Organisation (ISO).

As there is no certification system in place which distinguishes between the terms ‘degradable’ and ‘biodegradable’ in South Africa, it has meant that companies are able to punt their packaging as being biodegradable and therefore environmentally-friendly.

The Seven Sins of Greenwashing

Your eyes aren’t deceiving you, but the labels might be. There are more products claiming to be green on the shelves of stores these days, however those ‘all-natural’ and ‘organic’ products are likely committing at least one of the Seven Sins of reenwashing, by not telling the complete truth. Between 2007 and 2009, the in-store availability of so-called ‘green’ products has increased between 40% and 176%, with 98% of products surveyed still committing at least one Sin of Greenwashing, according to a report on the Seven Sins of Greenwashing released by TerraChoice Environmental Marketing.


1. The Sin of the Hidden Trade-off, which occurs when one environmental issue is emphasized at the expense of potentially more serious concerns. In other words, when marketing hides a trade-off between environmental issues. Paper, for example, is not necessarily environmentally preferable just because it comes from a sustainably harvested forest.

2. The Sin of No Proof. This happens when environmental assertions are not backed up by evidence or third-party certification. One common example is facial tissue products that claim various percentages of post-consumer recycled content without providing any supporting details.

3. The Sin of Vagueness, which occurs when a marketing claim is so lacking in specifics as to be meaningless. “All-natural” is an example of this sin. Arsenic, uranium, mercury, and formaldehyde are all naturally occurring—and poisonous. “All-natural” isn’t necessarily “green.”

4. The (new) Sin of Worshipping False Labels. This is when marketers create a false suggestion or a certification-like image to mislead consumers into thinking that a product has been through a legitimate green certification process. One example of this sin is a brand of aluminum foil with certification-like images that show the name of the company’s own in-house environmental program for which there is no explanation.

5. The Sin of Irrelevance. This sin arises when an environmental issue unrelated to the product is emphasized. One example is the claim that a product is “CFC-free,” since CFCs are banned by law.

6. The Sin of Lesser of Two Evils, which occurs when an environmental claim makes consumers feel “green” about a product category that is itself lacking in environmental benefits. Organic cigarettes are an example of this sin.

7. The Sin of Fibbing. This is when environmental claims are outright false. One common example is products falsely claiming to be Energy Star-certified.

Growing compostable plastic bag use


Confusion might still lingers on what bioplastics really mean but their use is definitely growing.

In the compostable bag sector, SunChips maker Frito Lay announced that they are going to launch in 2010 the world's first fully compostable chip bag of its kind, with the bag fully decomposing within 14 weeks - when placed in a compost bin or pile. See the video below!

The company will use NatureWorks polylactic acid plastic Ingeo (usually made from corn) in the packaging's outer print web film and inner barrier web film. The adhesive layer gluing the two films together will be made with other "also" eco-friendly material.

Frito Lay said it did not replace all the materials with PLA as there is currently not enough PLA supply available at this time and there are still work needed to maintain the packaging's quality. The company, by the way, also explains the difference between degradable, biodegradable, compostable and renewable plastics.

Meanwhile, KMart in Australia last month said that they are going to use bioplastic shopping bags for their 12 stores in South Australia using Cardia Technologies Limited's Biograde compostable bags. South Australian Government's ban on plasticcheckout bags takes effect on 4 May 2009.

In Minnesota, the state's Department of Administration, Materials Management Division picked Northern Technologies International's Natur-Tec(r) Compostable Plastic Bags for various state agencies' use.

In addition, under Minnesota's Cooperative Purchasing Venture (CPV), entities such as counties, cities, townships, school districts, charitable organizations and community clinics are also eligible to procure Natur-Tec(r) compostable plastic bags from NTIC at the prices and terms negotiated with the State.

Over-Packaging : Reduce before Recycle

Ever order something and it arrives in a really big box—a much-too-big box? Paper products, such as the cardboard boxes used for shipping and packaging, make up one-third of the municipal solid waste in the U.S. Could we cut back?

Consumer Reports says people routinely send in letters complaining about small items arriving in way too much packaging. To check the problem, Consumer Reports ordered small items from 13 companies, including Avon, Staples, drugstore.com, Oriental Trading Company, and Best Buy. Consumer Reports was really surprised to find that so many tiny items came in boxes that were way too big.

For example, a package from drugstore.com contained just one lip balm. A box from Avon arrived with just one lip balm as well. Inside a box from the Oriental Trading Company—just one small vial of beads. And a box from Staples—it could easily fit 200 pencils but contains…just one.

Not everything arrived over sized. A small pack of batteries ordered from Quixtar came in a small shipping envelope.

Less packaging could make a real difference. If Americans cut back the use of cardboard from 100 tons to 90, it would save more than 5,300 pounds of waste…20,000 gallons of waste water…and more than 34,000 pounds of carbon dioxide equivalent.

Some companies, such as Avon, Staples, and Lands End, told Consumer Reports that they recycle thousands of tons of cardboard a year.

Plastic bag obsession is carrier for environmental ignorance

It's time to refocus; plastic bags are not the scourge of the planet, their biggest evil is to distract us from more pressing causes.

Don't get me wrong – I don't like plastic bags either. We use too many of them, just as we use too many of all the earth's resources. They litter the countryside and cause problems for wildlife when they end up in the sea. But their total impact is microscopic by comparison to almost anything else we do. As environment writer George Marshall records in his excellent book Carbon Detox, our annual average consumption of bags produces 5kg of carbon dioxide a year. Total average emissions are 12,500kg.

Plastic bags aren't even a very large component of domestic waste. Plastics in general – according to a study by South Gloucestershire district council – account for 18% of total household waste. Plastic bags account for 18% of the plastic, which means 3.2% of total waste. Clingfilm (23% of domestic plastic waste) produces a greater proportion than plastic bags.

So why this fetishisation? Because dealing with plastic bags is easy. Easy for the government, easy for retailers, easy for shoppers. It threatens no one, makes money for the shops (if they charge for their bags) and ensures that everyone feels better about themselves, while continuing to trash the biosphere just as we did before.

Bioplastics: Concerns and Responses

London Bio Packaging (LBR) believes that bio based plastics are the most environmentally friendly materials available and play an important role in creating a more sustainable society.
---
Recently some have challenged whether bio-plastics are actually environmentally friendly. London Bio Packaging raises these issues and responds to them.

The Concern: Bio-plastics do not break down in landfill and if they do they create methane.

LBP Response:

In the UK the majority of landfill sites are now containment sites. This means that the landfill is lined and leachate and gas that is produced is collected. Bio-plastics will break down into compost in as little as eight weeks in an industrial composting facility. There are currently over 100 composting facilities in the UK and many more are being planned and built. Anaerobic digestion (an in vessel form of composting) takes what is apparently a waste product (such as post use food and bio packaging) and turns it into two useful commodities: compost and energy!

It should also be remembered that the problems of landfill apply to other wastes such as conventional plastics.

Mostly conventional plastics are sent to landfill because very few forms other than bottles can be recycled in the UK.

London Bio Packaging has developed its own closed loop composting system whereby bio packaging and food waste is collected and taken to a composting facility. All that is left at the end of the closed loop process is compost that farmers use to fertilize fields. (The fields could then grow more crops to make packaging!)

One key environmental benefit of using bio-plastics is they have a lower carbon footprint thus helping to combat climate change. Bio-plastic (PLA) emits 0.75 kilos of carbon dioxide per kilo of resin as compared with conventional plastic (PET), which emits 3.4 kilos of carbon dioxide per kilo. So bio-plastic emits 77 percent less carbon dioxide. This is not just a marginal difference but a hugely important step in fighting climate change!

The Concern: Bio-plastics use crops that would otherwise be used for food.

LBP Response:

The amount of corn used worldwide for bio-plastics in 2007 was about 250,000 tonnes. In 2007 the US alone produced 332 million tonnes of corn (in addition the US grew numerous other food crops including sorgum grain - 12.8 million tonnes, rice - 10 million tonnes and soybean - 70 million tonnes).

The percentage of US food production that would be used for worldwide bio-plastics production is 0.0005 percent. This does not take into account all the other food produced worldwide. This cannot be considered to have an effect on food scarcity, especially when compared to bio-fuels which used approximately 18 percent of US grain production in 2008. The raw material for bio-plastic production is plant starch. With technological developments, soon the starch will be taken from any biomass or crop waste and not the crop parts used in food production.

The Concern: If bio-plastics are sent to recycling facilities they will contaminate the waste stream.

LBP Response:

Currently bio-polymers account for a small percentage of overall conventional plastics use. As such they currently have little affect oil based plastic recycling.

Other polymers, i.e. PP or PVC, are already in widespread use and can also contaminate recycled PET plastic waste streams, so this is not something unique to bio-polymers. It is also possible to separate bio-plastics from the waste stream in the same way as other materials. More modern sorting/recycling facilities already have the ability to do this, but it may require investment in infrastructure in some recycling facilities.

But, the future always requires investment! Otherwise we will be stuck using oil, emitting lots of carbon and sending waste to landfill. The environmental costs of not developing sustainable materials and processes will outweigh the investment in bio-polymers.

The government must lead on putting in place the infrastructure for dealing with bio-plastics and compostable waste. There are vested interests in both the packaging industry and waste management organisations to focus on oil based plastics and diverting waste from landfill at the expense of real sustainable materials and solutions.

The Concern: Degradable plastics break down into tiny pieces which pollute the environment.
---
LBP Response:

Yes degradable plastics (also called oxy degradable plastics) have even more negative environmental impacts than conventional oil based plastics! Degradable plastics are different from biodegradable plant-based plastics (bio-plastics). They are conventional oil based plastics with additives that break them down into tiny pieces.

Degradable plastics do not have the renewable resource and low carbon benefits that plant based bio-plastics have, but also when they break down into tiny pieces, they pollute the environment. Research suggests the tiny pieces spread through the eco system and act as transporters for nasty chemicals such as DDT.

The concern: Recycled plastics are preferable to bio-plastics.

LBP Response:

Recycled plastics are a strong environmental option where good infrastructure for recycling exists (such as with bottles) or where bio-plastic applications are not currently suitable (i.e. some microwaveable packaging). Recycled plastics (like rPET) provide many environmental benefits over conventional virgin plastics and LBP does offer rPET products. However, recycled plastics are not ideal and not a long term solution. They still rely on a large percentage of oil (about 50 percent recycled is a standard maximum). Oil is unsustainable and sooner or later will run out! Importantly the carbon emissions associated with recycled plastic production are higher than bio-polymers.

Packaging solutions for climate change

Minimising food packaging, boosting processing efficiency and avoiding food waste could make powerful contributions to reducing greenhouse gas emissions from the US food industry, according to a new report.

“Processing can be on the order of 10-20 per cent of a food product’s life cycle GHG [green house gas] impact, especially for prepackaging meals or other prepared foods. Most of this impact comes from the heat and electricity requirements of processing equipment,” write the report’s authors.

YDreams invente le quotidien interactif
