\'biodegradable\' plastic bags may not be as eco-friendly as thought

Plastics, which are often labeled as biodegradable or biodegradable, are found to have uncertainties about their impact on the natural environment.
Handbags, bins and flexible packaging made of ordinary plastics containing a small amount of chemicals are also not suitable for recycling, reuse or composting with other plastics, research from Loughborough University found.
After research funded by the Ministry of Environment, Food and Rural Affairs, the ministers called on the industry not to claim that plastics are better for the environment than conventional plastics. And the Co-

Degradation plastics contain additives that help them degrade into smaller pieces faster with the help of heat or light.
They then have to be biodegradable, a process caused by microorganisms.
Adding metal compounds to plastics did not improve their environmental properties, the report said, \"may have some negative effects \".
Researchers say it is difficult to estimate how long plastic degradation will take, although it has been suggested that it will take about two to five years if plastic is excluded from an open environment in the UK.
But in the absence of oxygen, they do not degrade, so it is unlikely that they will break down in the landfill, because most of the plastic in the landfill will eventually be broken down.
The biodegradable process occurs only when the plastic is initially broken into smaller pieces, a process that takes place very slowly-many times slower than a stackable bag.
One of the claims made for oxo
Degradation of plastics is that they reduce the garbage because they are biodegradable, but the report says they will still lie around for a few years before they break down in the environment.
There is concern that the degraded fragments of plastic may have an impact on nature and may be consumed and accumulated by insects, animals and fish.
The report says there is no evidence in any case whether or not this is causing problems for wildlife.
The study warns that consumers may be confused by labeling products as \"biodegradable\" and may put them into compost materials-although it will take longer to break down.
These additives also make plastics unsuitable for recycling and reuse with mainstream plastic packaging, especially for long-term storage, as they start to break down.
The report requires that the plastic be described as \"biodegradable\" to better explain exactly how the plastic will break down, or replace it with the correct treatment.
Environment Minister Dan Norris said: \"Today\'s research clearly tells us that consumers may be confused by some claims about oxo --
