Have you ever seen the numbers on the bottoms or sides of plastic containers, and questioned what they imply? A small quantity is positioned on all plastic containers, normally clear in colour and surrounded by three small arrows, indicating that they’re recyclable.


These numbers are known as Resin Identification Codes (RIC), and vary from one to seven. The numbers point out the form of plastic that they’re, which makes recycling a lot less complicated for you and your neighborhood.
The numbers on plastic containers can also inform you what the plastic is comprised 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 don’t seem to be price efficient! That’s as a result of plastic can’t actually be recycled.
The phrase recycling means taking a cloth, melting it down, and turning it again into itself again and again. This may be achieved with glass and steel, each of which will be remelted and remade into jars or cans endlessly. However, some supplies degrade over time, and may solely be recycled perhaps a few times till the fabric breaks down an excessive amount of, and may now not be reformed into what it as soon as was.
That is known as downcycling.
Plastic is much like paper in that it could solely be downcycled. Plastic water and soda bottles, for instance, will not be normally turned again into bottles. As a substitute, the plastic is damaged down and used for one thing extra primary like fleece material or plastic lumber. Which means virgin plastic comprised of fossil fuels remains to be required for the manufacture of latest plastic bottles.
One of many hazards of plastic is that it can’t biodegrade, ever. As a substitute, 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 function 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 mushy 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 typically new containers.
PET is taken into account protected, however proof reveals it could truly 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 had been greater than 100 occasions the everyday stage present in clear groundwater (2 components 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. Additionally it is 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 may possibly 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 baggage. 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 substances. In one study, 95 p.c of all plastic merchandise examined had been constructive for estrogenic exercise.
This implies they’ll disrupt your hormones and even alter the event of your cells, which places infants and kids at even larger danger. 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. Additionally it is 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 incorporates quite a few poisonous chemical substances together with lead and DEHP, a kind of phthalate used as a plastics softener. As if the lead weren’t dangerous sufficient, phthalates are thought-about “gender-bending” chemical substances which trigger the males of many species to grow to be extra feminine. These chemical substances disrupt the endocrine programs of wildlife, inflicting testicular most cancers, genital deformations, low sperm counts and infertility in quite a few species, together with polar bears, deer, whales, otters, and frogs, amongst others.
Scientists consider phthalates trigger comparable dangerous results in people. If your property has versatile vinyl flooring, a plastic bathe curtain, or these padded playmat flooring for youths (typically utilized in day cares and kindergartens, too), there’s probability it’s comprised of PVC. PVC flooring has additionally been linked to power illnesses like allergy symptoms, bronchial asthma and autism.
PVC is likely 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 baggage, produce baggage, squeezable bottles in addition to coated paper milk cartons and scorching/chilly beverage cups. It’s normally downcycled into transport envelopes, trash baggage, and compost bins.
Whereas LDPE doesn’t include BPA, it could leach estrogenic chemical substances, very similar to HDPE.
#5 – PP (polypropylene)
Polypropylene is utilized in straws, yogurt containers, and syrup, ketchup, and drugs bottles. It’s normally downcycled into ice scrapers, brooms, brushes, rakes, storage bins, transport 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 substances.
#6 – PS (polystyrene)
Polystyrene can be recognized 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 decent meals and drinks makes it leach toxins much more, so attempt to keep away from scorching 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 comprised of different plastic resins not described above, or these comprised of a mix of plastics. Whereas there are numerous various kinds of #7 plastics, the most typical embody 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 positive what varieties of toxins could also be in #7 plastics since they differ a lot, however there’s an excellent probability that if they’re polycarbonates, they include bisphenol-A (BPA), or the equally regarding chemical created to switch BPA, often known as Bisphenol-S (BPS).
BPA and BPS are each endocrine disrupters that intrude along with your physique’s hormones, affecting your temper, progress and improvement, tissue perform, metabolism, sexual perform and skill to breed. Over 6 billion kilos of BPA are produced annually, so it’s no marvel that the CDC found that 93% of Individuals over the age of 6 have BPA of their urine and bloodstream!
Among the best concern surrounds publicity to BPA and BPS throughout being pregnant, which might result in chromosomal errors, spontaneous miscarriages and genetic injury. However proof can be very sturdy that these chemical substances are harming adults and kids, too, inflicting decreased sperm high quality, early puberty, disrupted reproductive cycles and ovarian dysfunction, most cancers, and coronary heart illness.
Research has discovered that “larger BPA publicity is related to common and central weight problems within the common grownup inhabitants of the USA.” Another study discovered that BPA is related not solely with weight problems, but additionally with insulin resistance, which is an underlying think about many power illnesses.
Hidden Sources of Plastic Toxins
Many people know by now to search for “BPA-free” bottles and containers. (For those who didn’t know that, now you do!) However, plastic is in all places, so toxins will be discovered within the locations you won’t learn about, like:
- BPA-free plastic bottles (can use BPS as a substitute),
- the within lining of practically 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 style gadgets (phthalates, mercury and lead),
- cash register receipts (BPA/BPS), and extra.
Plastic Containers Can Hurt Your Well being
Among the best issues you are able to do in your well being, particularly if you’re wrestling with a power situation, is to get rid of as a lot plastic out of your life as doable.
Many medical doctors and scientists have legitimate issues about consuming meals and drinks in plastic containers. Ample proof means that dangerous chemical substances 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, scorching water or the solar.
These poisonous chemical substances—discovered within the majority of plastic, PVC and vinyl gadgets made in the present day—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 scorching automobile.
The Good Facet of Plastic
There are some good makes use of for plastic. Whereas single-use plastic like product packaging and procuring baggage must be phased out, plastic is an incredible asset to the medical neighborhood for issues like syringes and IV tubing. It’s sturdy, so for issues like playground tools, benches or computer systems, plastic could be a a lot longer-lasting alternative than supplies like wooden or steel. Additionally it is light-weight, which means items will be shipped farther utilizing much less gasoline throughout transport.
In the end all of us have to lower our reliance on plastic to minimize its impression on the surroundings, and transition to reusable items and plant-based plastics as a lot as doable. Lastly, it’s vital to remember that, though you’re recycling your empty detergent bottles, they don’t seem to be as recyclable as you suppose.
