Storing leftovers has been a way to extend the fun of dining during the holidays for a long time, and many cabinets have plastic buckets that wrap together with other containers.
Although they reduce food waste, some containers pose a greater burden on the atmosphere and potential health than others.
Storing food in reusable containers helps reduce environmental impacts associated with a single container
Use containers, but have more knowledge of containers in various forms (
Including the resin type of plastic container)
Can help you make better choices.
Resin code plastics are generally classified by one of the seven resin codes indicating the type of resin used (
The code is usually located within a modest triangle at the bottom of the container and bottle)
The details are as follows: 1 polybenzene diester (PET or PETE)-
Products: s2 high density polyethylene (soft drink bottles, water bottles and some drug containers (HDPE)-
Item: bottle of milk jug, detergent, shampoo and oil ,(also some toys)
3 PVC (V or PVC)-
Products: pipes, shower curtains ,(and some clip-wraps)
4 low density polyethylene (LDPE)-
Products: packaging film, grocery bags5 polypropylene (PP)-
Products: syrup bottle, yogurt bucket, bottled polystyrene (PS)-Items: Single-

s, some na gene water bottles, complex environmental pollution, although most industrial processes are related to specific by-products, additional toxic emissions can be generated by making plastic resin than making glass
Based on the Berkeley plastic workforce, 16 ounces were manufactured.
PET bottles emit 100 times more toxic to air and water than bottles of the same size produced with glass.
In a report of 1996, the process force noted that the plastic market contributed 14% from the most toxic industrial releases-
Including benzene, benzene and chlorine--in to the air.
Other key emissions in the plastic production process include sulfur oxides, nitrogen oxides, methanol, ethylene oxides and volatile organic compounds. Petroleum -A Non-
Renewable resources plastics are created by oil.
Renewable resources for new fossil reserves need to be continuously mined.
Just because the formation of fossil fuels takes millions of years, they may be a limited and ultimately a consumable energy source.
The United States is the world\'s second-largest oil producer, with only 4% of the world\'s oil reserves, but consumes 30% of the world\'s oil every year.
By choosing to switch from plastic to renewable and recyclable packaging, we are able to save this beneficial resource and minimize our dependence on oil.
According to the U. S. Environmental Protection Agency, the United States handled only over 30 million tons of plastic in 2008.
Although plastic recycling continues to grow, it increased by 580% from 1990 to 2001, two of them.
1 million tons of plastic were recovered in 2008, but the actual situation is that the recovery rate is still very low (
Only about 7% of plastic is recycled each year).
In addition, buyers generally think that the coded symbols on plastic containers mean that when the symbols only determine the resin base from the plastic, the item is recyclable and not all recycling plans accept all of them.
Businesses should be urged to use recycled plastics, and citizens should encourage their states to pass and enforce the bottle Act and other legislation that supports the promotion of recycling.
In the process of plastic manufacturing, use and disposal, personal health is greatly threatened, each from ethylene monomer, one of the many standard development blocks of plastic, from the problem of chemicals added to provide plastic solutions, they have the ideal overall performance.
Some examples of compounds related to plastic manufacturing are described below. [sidebar1]
Even at low doses, dioxin is very toxic and is discharged into the atmosphere and waterways when most plastics are manufactured and burned.
Although the dioxin levels in the US atmosphere have declined over the past 30 years, they break down so slowly that some of the dioxin released in the past will still be in the atmosphere after many years.
In the 2000 final draft assessment of the health impact of dioxin, the United StatesS.
Environmental Protection Bureau (EPA)
It is concluded that there is a potential for a range of adverse effects of dioxin on human health.
The EPA report estimates that the threat of cancer in typical Americans from exposure to dioxin could be as high as 1,000--
It is 1,000 times higher than the normal number of people within a million of the government\'s current \"acceptable.
Dioxin is also an endocrine disruptor that interferes with all natural hormone signals in the body.
In addition, dioxin exposure can impair the immune process and may affect reproductive and child improvement.
Several preservation of PhthalatesQuite
Packaged meats, cheeses and other foods sold at delis and grocery stores are packed in PVC.
In order to soften 3 PVC plastics and other plastics into flexible forms, producers have added several toxic chemicals commonly referred to as \"plasticizer\" during the production process.
When the PVC is in contact with the food, traces of these chemical compounds, known as adipates and phthal salts, may leak out of the PVC.
Phthalate was found to interfere with all production of animal male reproductive hormones and is most likely to have an equal effect on humans.
Their role in animal research has been well recognized, including a decrease in testosterone levels, a decrease in sperm count, and a decrease in sperm quality.
Exposure to neighboring benzene Ester in the course of improvement may also lead to deformity of male reproductive and testosterone cancer.
Young children and developing fetus are the biggest threats.
In action to address these issues, in 2008, Congress banned the use of six phthal salts in children\'s toys and articles. Bisphenol-
A batch of 7 polyester bottles (
Like baby bottles)
Microwave equipment, consumer appliances and plastic coating for the production of metal cans with double phenol
A, A chemical invented in the 1930s in the search for synthetic estrogen. Bisphenol-
As you get older, A can penetrate into food from canned or polycarbonate bottles.
A lot of research on double phenol-
A as A hormone disruptor, A chemical that changes the activity of A typical hormone in the body.
In the early days of life, the experimental animals were exposed to this chemical.
Cancer modification in the breast and prostate;
The improvement of the brain, resulting in abnormal behavior and early onset of puberty;
For example, abnormal reproduction, reduced sperm count, hormonal regulation, increased prostate, abnormal egg chromosome count, obesity and insulin resistance, a condition before diabetes is improved.
There is no doubt that there is concern that BPA may cause similar health problems in humans.
More than 90% of the average population contains BPA, which is close to the level that may cause injury in animal studies.
It happened that someone showed AntimonyPET plastic water bottles how to dissolve antimony into water.
A new study by Bill Shotyk, a researcher at Heidelberg University, published in Volume 8, Issue 2 of the Journal of environmental monitoring, shows that the amount of antimony in PET water bottles exceeds the level of accurate discovery of water sources.
Based on Shotyk, customers should really not worry about drinking water bottled with PET plastic, as the water content in the water is lower than the standard for safe drinking water.
Nevertheless, it is important not to forget that leaving water in any plastic bottle for a longer time frame will allow chemical leaching.
Solutions for glass, ceramics and glass, ceramics and pottery are the safest option in terms of food packaging and storage, because when in contact with food, they don\'t usually filter any suspicious chemicals.
Compared to plastic recycling that can produce toxic chemicals, glass recycling is more eco-friendly. Safer plastics-
When deciding to use a plastic container, 1 Pet, 2 high density polyethylene, 4 low density polyethylene and 5 pp, even those that you will use more than once, choose something that may be accepted for recycling in your location.
1 PET is ideal for high recyclability.
Although there is one PET reusable container, the analysis shows that,
Using a bottle causes bacteria to occur in the thread.
Many reusable containers are made of different typical recycled plastic 2 high density polyethylene.
Quantity 4 of low density polyethylene and 5PP plastics although not widely recycled, there is also a great possibility because, like 2, most studies do not show any carcinogens or endocrine disruptors
Some bread and frozen food bags and extruded bottles are made of 4 kinds of plastic, and some ketchup bottles, yogurt and artificial butter barrels are made of 5 kinds of plastic.
Bio-base compost plastic made of corn, compost plastic (
Poly-C Ester or PLA)
Or other plants, which are decomposed by bacteria when compost in commercial compost technology.
Although the bags produced by PLA look, really feel and smell like typical plastic bags, more than half of them in about 12 days of commercial advertising will break down, compared to standard plastic bags, this may take 100.
Sadly, the lack of compost facilities in some cities means that a large amount of plastic will be completed in a landfill, and this atmosphere will greatly slow down their decomposition.
Still, bio-based plastics, such as biofuels, are a construction market that, if created properly, can offer some possible renewable options for fossilsfuel-derived, non-
Ideally, you need to obtain bio-based compostable plastics from agricultural residues (
Like sugar cane, waste produced by sugar cane)
Otherwise it will be considered a waste.
Be wary of compost plastic from other varieties produced in plants
Derivative materials mixed with oil
Derivative solutions that normally do not break down completely may end up in the food chain.
Aluminum and stainless steel food storage containers produced by aluminum are an option for plastics because aluminum is recyclable, relatively cheap and even has a heating capacity.
Nevertheless, aluminum extraction is indeed power intensive, so reuse containers like old jars, looking for new containers made of recycled contents material, when containers reach the end point of precious life,
The container produced in stainless steel is also a good choice, not only because the material is 100% recyclable, but also because the stainless steel is easy to clean, there are no harsh compounds.
Low stainless steel-
The cost is high, attractive, and will not react to food through cooking.
What happens to plastic at higher risk
3 PVC, 6 PS, 7 others (
It\'s usually polyester)
Sometimes it is found in transparent food packaging that PVC is the second most commonly used plastic on Earth and is toxic plastic for our health and atmosphere.
It is manufactured and burned to release dioxin, a powerful carcinogens and hormone disruptors.
PVC is the main component of PVC, it is indeed a certain human carcinogens, and also poses a threat to workers by manufacturing.
In contact with food, especially hot, fat-rich foods, PVC may also filter chemicals such as fat and neighboring benzene ester, which happens to be shown to cause birth defects in mice, and cause damage to the liver, kidneys, lungs and reproductive systems.
In addition, most community recycling projects generally do not accept PVC, so the vast majority of vinyl will eventually be disposed of in landfill or incinerator.
While many businesses have agreed to limit or phase out PVC, we still have a long strategy to advance the ban on the use of this \"toxic\" plastic.
Polystyrene, 6 PS, is usually identified in foam containers and cups, sometimes in transparent disposable take-out containers, plastic tableware and cups.
It is best to prevent this plastic because PS will most likely dissolve the styrene into the food it touches.
The international cancer research agency of the global welfare organization believes that styrene is a viable human carcinogenic substance, and it is also likely to destroy hormones or affect reproduction. Polycarbonate (
In quite a few plastics marked as 7, \"other \"-
Do not be confused with compostable plastics that are also marked as 7
, Usually identified in baby bottles, 5-
The lining in the gallon water bottle and the food tank can release its main ingredient-double phenolA (BPA)
Become liquid and food.
A study conducted by Kumamoto Prefecture University in Japan concluded that polycarbonate bottles containing hot liquids would filter more double phenol-
Despite the fact that quite a few tissues are starting to stay away from BPA, since 95% of the available child bottles are made of polycarbonate made of BPA, parents have a proper concern.
The National Environmental Trust Fund proposes to switch to polycarbonate-
Free baby bottles, such as baby bottles made of glass or polypropylene (5)plastic.
Microwave in plastic although \"microwave oven is suitable
The \"safe\" or \"microwave\" labels on plastic containers only indicate that they should not melt, break or break up when used in microwaves, labels do not guarantee that the container will not dissolve chemicals into the food when heated.
S. Department of Agriculture also warned on its website not to use microwave ovens
Use containers that are not used for this target, such as takeout platters and artificial butter barrels.
Based on FDA, microwave-
The safe plastic wrap must be placed more loosely than the food to ensure that the steam can escape and there is no direct contact with the food.
For the sake of safety, it is best not to heat the food with plastic, nor to use a glass or ceramic container with a lid.
In no event shall plastic storage bags, grocery bags, newspapers or aluminum foil be used in the microwave oven.
Just here, you can follow the following ideas to reduce exposure to plastic and toxic substances in your residence: stay away from being single
Use disposable containers, place food in glass or metal containers, stay away from heated food in plastic containers, bring your personal containers to salad bars, yogurt shops, etc. -
No matter where you are, especially when cooking or heating food, plastic tableware and tableware can be used;
Use a stainless steel or wooden appliance that appears in a solution of recycled paper. Use wood as a replacement for plastic cutting boards, spray the boards with vinegar mist, then add hydrogen peroxide and kill bacteria when buying plastic wrap
Food packaged in a supermarket or deli, cut a thin layer from where the food is in contact with all the plastic, and then the retailer places the rest in a glass or ceramic container, or non-PVC plastic wrap (
See shopping ideas)
It is also possible to write a letter to food and beverage producers in plastic packaging to indicate your concerns about plastics
Especially if their packaging is 3, 6 and 7.
Tell them that you will be actively looking for items packed in safe, reusable glass, metal and recycled paper.
Producers are required to obtain a mailing address by making a toll call
Free question/comment line, usually listed on the back of the item;
Alternatively, they can also find their mailing address on their website.
