Are bioplastics better for the natural world than conventional plastics?<\/h3>\n

Confusion among terms like bioplastics, bio-based and biodegradable plastics makes it hard to discern - and make - the natural world friendly choice.<\/strong><\/p>\n

Have you ever <\/span>stood in front of a supermarket shelf and wondered if you should buy that product made from bioplastics rather than the conventional kind? Many people assume all bioplastics are made from plants and can break down completely in the natural world. But that\u2019s not the case.<\/span><\/p>\n

The term \u201cbioplastics\u201d is actually used for two separate things: bio-based plastics (plastics made at least partly from biological matter) and biodegradable plastics (plastics that can be completely broken down by microbes in a reasonable timeframe, given specific conditions). Not all bio-based plastics are biodegradable, and not all biodegradable plastics are bio-based. And even biodegradable plastics might not biodegrade in every space. Sounds confusing? It certainly is.<\/span><\/p>\n

\u201cThere are a lot of bioplastics or materials that are called bioplastics that are not biodegradable,\u201d says <\/span>Constance I\u00dfbr\u00fccker, head of natural world affairs at the industry association <\/span>European Bioplastics<\/span><\/a>. <\/span><\/p>\n

For some plastics, the same polymer chains can be made from renewable sources. The resulting bioplastics are chemically identical to their fossil counterparts. PET, for example \u2014 short for polyethylene terephthalate, which is the stuff most bottles are made of \u2014 can be synthesized from fossil fuel products or plants like sugarcane. The resulting material is the exact same. Such non-biodegradable bioplastics behave in the natural world just like conventional plastic and persist for an unknown but long amount of time.<\/p>\n

\"\"<\/span><\/p>\n

Not only that, but <\/span>none of the standards for plastics<\/span> labelled as biodegradable or compostable today makes them suitable for disposal in the open space. Given that, can bioplastics play a role in tackling the natural world's problems? Or are they merely greenwashing? The most accurate answer is, it depends.<\/span><\/p>\n

Tackling confusion<\/span><\/h3>\n

There\u2019s no doubt, bioplastics are still plastics. Just because some of them are made from plants or have the potential to biodegrade under limited conditions, they can\u2019t be touted as \u201cplanet-safe.\u201d For the ones that claim to biodegrade or compost, the fine print is crucial.<\/span><\/p>\n

So check the label: What does it say? Where and how is it supposed to biodegrade? How can you safely dispose of the product?\u00a0<\/span><\/p>\n

Finally, be cautious when you read that a material is oxo-biodegradable*.<\/span>\u00a0These are conventional plastics like polyethylene mixed with metal compounds that make them fall apart faster. According to a\u00a0report by the United Nations Environment Programme (UNEP)<\/a>, it hasn\u2019t been proven that they truly biodegrade, and it is feared they might just accelerate microplastic pollution. Similarly, European Bioplastics warn that so-called \u201cenzyme-mediated degradable plastics<\/a>\u201d aren\u2019t truly biodegradable.<\/span><\/p>\n

Reduction remains key<\/span><\/h3>\n

There\u2019s no doubt, bioplastics are still plastics. Just because some are made from plants or have the potential to biodegrade under limited conditions, they can\u2019t be touted as \"planet-safe.\" For the ones that claim to biodegrade or compost, the fine print is crucial.\u00a0<\/span><\/p>\n

The plastic industry projects strong growth in production, and biodegradable plastics won\u2019t solve the plastic crisis, so tackling consumption remains key. \u201cBy just reducing the amounts and the types of different packaging that we have in our supermarkets, we can do a lot, without developing novel materials,\u201d says Wurm.<\/span><\/p>\n

Even European Bioplastics\u2019 I\u00dfbr\u00fccker thinks that might very well happen. \u201cMaybe not in 5 or 10 years, but as the problems keep growing, plastic production might go down one day, because it\u2019s just too much.\u201d<\/span><\/p>\n

*Plastic bags that biodegrade to nothing?<\/h3>\n
\n

A British company which makes what are called \"Oxo-biodegradable\" bags says they break down in the natural world \"like a leaf, only quicker\", and the technology is being widely used across Africa and the Middle East. So if they are that good, why are they facing a possible ban by the European Commission?<\/p>\n<\/div>\n<\/div><\/div>
