trash talk: should we reuse those empty plastic food tubs? - polycarbonate plastic
Recently I watched a movie where one of the main characters put scallops in a plastic container into the microwave to heat up.
I must admit, I backed down.
Is it safe to microwave food in plastic containers?
Should we reuse yogurt and other containers to store food?
Should we put them in the dishwasher?
One of my favorite plastic buckets to reuse is two
Polyethylene barrels with elevated density (
Plastic No. 2)
I bought buttermilk.
Perfect for homemade soup and dog food.
Should I keep putting it in the dishwasher?
The theme of many plastic compounds and their safety are daunting.
It is a sea of conflicting information, and it becomes even more vague due to some downright lies, vested interests and many questions about where the contaminants really come from.
Also, as noted by Fred Edgecombe, a senior PhD in the plastics industry and current technical advisor to the Canadian Plastics Industry Association, "People have chemical phobia. Understandable.
In addition to those who have studied carbon, hydrogen and oxygen atoms, who can understand these complex patch structures.
Ironically, the quality of making such a huge container of plastic --light and long-lasting —
As we did not properly dispose of the garbage, it has caused serious environmental harm, destroyed wildlife and produced garbage strips in two oceans. So, what to do?
What about my beloved buttermilk bucket?
Catherine Cooper, a senior fellow at the Canadian Environmental Law Society, recently published some guidelines for the use of plastics, who spent a lot of time studying chemicals in the environment.
She is most concerned about the two possible contaminants in some plastics: phthal acid salts and shuangphenol-
It is considered to be an endocrine system interference.
Both exist widely in the environment;
The jury disclosed the main sources.
The recent ban on BPA-containing bottles in Canada sounds good, right?
But Cooper pointed out that the greatest potential BPA risk for infants is in the womb, and the ban did not address maternal exposure through many possible sources, including white lining in food cans --
A major problem.
Receipts for Epoxies and cashier.
Cooper avoids food containers made of PVC (category 3)
, Is now only used for some food storage applications and some films, as well as 7 classes, which include hard polycarbonate plastics containing BPA.
She also bypassed 6 classes of polystyrene, mainly in takeout containers with foam and smooth plastic (
This may mean she eats well).
As for plastic categories 1, 2, 4 and 5: "I will not mix heat with plastic as a precaution.
This means that there is no plastic in the microwave or dishwasher and she lets the food cool before putting it into a plastic container.
Her concern about our lack of knowledge of environmental contaminants restricts her approach.
On the other hand, plastic has been designed for years to withstand the heat of the dishwasher, microwave oven and even oven.
Edgecombe pointed out, but we have to follow the instructions.
Look up the instructions on the container, both words and symbols, and use them accordingly. Polypropylene (number 5)
For example, it can be put into the dishwasher and microwave oven and soft at about 80 degrees Celsius.
Many polyacrylic milk barrels are now labeled as dishwasher safe boxes. High-
Density Polyethylene (2)—
My buttermilk bucket.
With a lower melting temperature 110C-125C.
I was told that what the dishwasher was worried about was not that the tub would break down and release the chemicals, but that the heat from the drying cycle would distort it.
Now I'm going to go ahead and put it in the dishwasher: It's a heavy job and I haven't had any problems so far.
I will not be afraid to reuse pets (1)water bottles.
I want to use a Styrofoam coffee cup (
Recycling in Toronto)
But I don't use polystyrene (
Can high fat temperature melt).
And I don't want to put any plastic in the microwave.
I prefer glass and porcelain.
But consider, given our distrust: PVC (3)
It is widely used for many purposes in hospitals, such as pipes, saline and blood bags.
Edgecombe said it.
The frightening neighboring benzene Ester in PVC actually helps to keep the red blood cells alive.
Talk about confusion.
More about these complex issues in future columns.
