Have you ever seen the numbers on the bottoms or sides of plastic containers, and puzzled what they imply? A small quantity is positioned on all plastic containers, normally clear in shade and surrounded by three small arrows, indicating that they’re recyclable.
These numbers are referred to as Resin Identification Codes (RIC), and vary from one to seven. The numbers point out the sort of plastic that they’re, which makes recycling a lot easier for you and your neighborhood.
The numbers on plastic containers can also let you know what the plastic is constituted of, and what results it has on human well being and the surroundings.
Is Plastic Actually Recyclable?
Despite nationwide recycling efforts, we at present recycle solely a measly 5 p.c of all of the plastics we produce. And more and more cities are shutting down their plastic recycling programs as a result of they aren’t price efficient! That’s as a result of plastic can’t actually be recycled.
The phrase recycling means taking a fabric, melting it down, and turning it again into itself again and again. This may be completed with glass and steel, each of which might be remelted and remade into jars or cans without end. Alternatively, some supplies degrade over time, and might solely be recycled perhaps a few times till the fabric breaks down an excessive amount of, and might not be reformed into what it as soon as was.
That is referred to as downcycling.
Plastic is much like paper in that it may possibly solely be downcycled. Plastic water and soda bottles, for instance, will not be normally turned again into bottles. As an alternative, the plastic is damaged down and used for one thing extra fundamental like fleece cloth or plastic lumber. Which means that virgin plastic constituted of fossil fuels continues to be required for the manufacture of latest plastic bottles.
One of many hazards of plastic is that it can not biodegrade, ever. As an alternative, plastic photodegrades, and that is very regarding. When uncovered to warmth and lightweight, plastic particles shred and break down into bits so small that they grow to be microscopic. Scientists and environmentalists are very involved in regards to the impact of these microplastics on the environment, particularly the dangerous position they play in human well being and the ocean ecosystem.

What Plastic ID Codes Imply
#1 – PET or PETE (polyethylene terephthalate)
PET is used for water and gentle drink bottles, mouthwash bottles, containers for condiments like nut butters and ketchup, and TV dinner trays. It’s normally downcycled into carpet fibers, fleece jackets, and generally new containers.
PET is taken into account secure, however proof reveals it may possibly really leach the poisonous steel antimony, which is used throughout its manufacture. One study checked out 63 manufacturers of bottled water produced in Europe and Canada and located concentrations of antimony that have been greater than 100 instances the everyday degree present in clear groundwater (2 elements per trillion).
The examine additionally discovered that the longer a PET bottle sits on the shelf—in a grocery retailer or in your pantry—the larger the quantity of antimony current. It is usually thought that the quantity of antimony leaching from these PET bottles will increase the extra they’re uncovered to daylight and warmth.
Brominated compounds have additionally been found to leach into PET bottles. Bromine displaces iodine within the physique, and is a central nervous system depressant. It could accumulate over time, and set off well being issues.
#2 – HDPE (high-density polyethylene)
HDPE is utilized in butter tubs, milk jugs, juice, family cleaner and shampoo bottles, in addition to cereal field liners and grocery luggage. It’s normally downcycled into decking, fencing, and plastic flower pots.
HDPE is commonly thought-about a low-toxin plastic, however like nearly all plastics, it has been discovered to launch estrogenic chemical compounds. In one study, 95 p.c of all plastic merchandise examined have been constructive for estrogenic exercise.
This implies they will disrupt your hormones and even alter the event of your cells, which places infants and youngsters at even larger threat. In this particular study, even HDPE products that were free of bisphenol-A (BPA) still tested positive for other estrogenic chemicals.
#3 – PVC (polyvinyl chloride)
PVC is utilized in plastic cooking oil bottles, deli and meat wrappers, shrink wrap, sandwich baggies, and plastic wrap. It is usually present in plastic toys, lunch packing containers, desk cloths and blister packs used to carry medicines. And it’s generally used to make jewellery and faux-leather purses, footwear and jackets. It’s normally downcycled into pipe, gutters, and packaging.
PVC comprises quite a few poisonous chemical compounds together with lead and DEHP, a sort of phthalate used as a plastics softener. As if the lead weren’t unhealthy sufficient, phthalates are thought-about “gender-bending” chemical compounds which trigger the males of many species to grow to be extra feminine. These chemical compounds disrupt the endocrine programs of wildlife, inflicting testicular most cancers, genital deformations, low sperm counts and infertility in a lot of species, together with polar bears, deer, whales, otters, and frogs, amongst others.
Scientists imagine phthalates trigger related dangerous results in people. If your house has versatile vinyl flooring, a plastic bathe curtain, or these padded playmat flooring for teenagers (typically utilized in day cares and kindergartens, too), there’s an excellent likelihood it’s constituted of PVC. PVC flooring has additionally been linked to continual illnesses like allergic reactions, bronchial asthma and autism.
PVC is without doubt one of the worst well being and environmental offenders.
#4 – LDPE (low-density polyethylene)
LDPE is taken into account to be low-toxin plastic and it’s utilized in bread luggage, produce luggage, squeezable bottles in addition to coated paper milk cartons and sizzling/chilly beverage cups. It’s normally downcycled into delivery envelopes, trash luggage, and compost bins.
Whereas LDPE doesn’t include BPA, it may possibly leach estrogenic chemical compounds, very like HDPE.
#5 – PP (polypropylene)
Polypropylene is utilized in straws, yogurt containers, and syrup, ketchup, and medication bottles. It’s normally downcycled into ice scrapers, brooms, brushes, rakes, storage bins, delivery pallets, and trays.
Whereas polypropylene is taken into account a low-toxin plastic that’s tolerant of warmth, at the very least one study discovered that polypropylene plasticware used for laboratory research did leach at the very least two chemical compounds.
#6 – PS (polystyrene)
Polystyrene can be identified colloquially as “Styrofoam,” and is utilized in egg cartons, disposable plates, cups and bowls, take-out containers, espresso cups, meat trays, packing supplies, and extra. It’s normally downcycled into gentle swap and outlet plates, packaging, and trays.
When heated, polystyrene can launch styrene, a suspected nerve toxin and carcinogen. Heating styrofoam or utilizing it for warm meals and drinks makes it leach toxins much more, so attempt to keep away from sizzling meals and drinks in polystyrene containers, and undoubtedly don’t use them within the microwave!
#7 – Other
#7 is a catch-all designation used to explain merchandise constituted of different plastic resins not described above, or these constituted of a mixture of plastics. Whereas there are numerous various kinds of #7 plastics, the commonest embrace 5-gallon-size water bottles, child bottles and different polycarbonate plastics. These plastics are sometimes downcycled into plastic lumber.
It’s tough to know for certain what forms of toxins could also be in #7 plastics since they fluctuate a lot, however there’s an excellent likelihood that if they’re polycarbonates, they include bisphenol-A (BPA), or the equally regarding chemical created to switch BPA, generally known as Bisphenol-S (BPS).
BPA and BPS are each endocrine disrupters that intrude along with your physique’s hormones, affecting your temper, development and improvement, tissue operate, metabolism, sexual operate and talent to breed. Over 6 billion kilos of BPA are produced every year, so it’s no marvel that the CDC found that 93% of People over the age of 6 have BPA of their urine and bloodstream!
A number of the biggest concern surrounds publicity to BPA and BPS throughout being pregnant, which might result in chromosomal errors, spontaneous miscarriages and genetic harm. However proof can be very robust that these chemical compounds are harming adults and youngsters, too, inflicting decreased sperm high quality, early puberty, disrupted reproductive cycles and ovarian dysfunction, most cancers, and coronary heart illness.
Research has discovered that “increased BPA publicity is related to common and central weight problems within the common grownup inhabitants of the US.” Another study discovered that BPA is related not solely with weight problems, but additionally with insulin resistance, which is an underlying consider many continual illnesses.
Hidden Sources of Plastic Toxins
Many people know by now to search for “BPA-free” bottles and containers. (In the event you didn’t know that, now you do!) However, plastic is all over the place, so toxins might be discovered within the locations you may not find out about, like:
- BPA-free plastic bottles (can use BPS as a substitute),
- the within lining of almost all canned food, soda and baby formulas (BPA/BPS),
- canning jar lids (BPA),
- toothbrushes and toothpaste tubes (BPA),
- plastic lunchboxes and toys (phthalates and lead),
- dental sealants and composite fillings (BPA/BPS),
- plastic and vinyl jewellery, purses, footwear and different vogue gadgets (phthalates, mercury and lead),
- cash register receipts (BPA/BPS), and extra.
Plastic Containers Can Hurt Your Well being
Among the finest issues you are able to do in your well being, particularly if you’re wrestling with a continual situation, is to remove as a lot plastic out of your life as doable.
Many docs and scientists have legitimate considerations about consuming meals and drinks in plastic containers. Ample proof means that dangerous chemical compounds like BPA, BPS, phthalates, xenoestrogens, dioxins, mercury, lead and antimony can leach from plastic containers into our meals and trigger well being issues—particularly when heated by microwave ovens, sizzling water or the solar.
These poisonous chemical compounds—discovered within the majority of plastic, PVC and vinyl gadgets made right this moment—are endocrine disrupters that intrude along with your physique’s hormones, which has been linked to weight problems, enlarged male breasts, earlier puberty in ladies, and elevated incidence of breast, prostate and different cancers.
To scale back your publicity to those toxins, keep away from reheating meals in plastic containers within the microwave, and use a plate, storage container or beeswax cowl as a substitute of overlaying meals with plastic wrap. Don’t purchase merchandise like TV dinners and microwave popcorn. Keep away from consuming meals or drinks which were heated in plastic containers, or left in a sizzling automotive.
The Good Aspect of Plastic
There are some good makes use of for plastic. Whereas single-use plastic like product packaging and procuring luggage must be phased out, plastic is an amazing asset to the medical neighborhood for issues like syringes and IV tubing. It’s sturdy, so for issues like playground gear, benches or computer systems, plastic could be a a lot longer-lasting alternative than supplies like wooden or steel. It is usually light-weight, which means items might be shipped farther utilizing much less gas throughout transport.
Finally all of us must lower our reliance on plastic to minimize its affect on the surroundings, and transition to reusable items and plant-based plastics as a lot as doable. Lastly, it’s vital to remember that, despite the fact that you might be recycling your empty detergent bottles, they aren’t as recyclable as you suppose.
