3D printing technology to be fully Eco-friendly.3D printing technology uses large amounts of energy, larger than the amount used by milling and drilling machines.
If you think about failed prints you may somehow eventually recycle the plastic.
Plastics products may take up to a thousand years to compost while PLA products compost within 3-6 months in a composting system.
PLA-  is made from renewable sources, such as starch – corn, potatoes, soy protein, cellulose, and lactic acid, cassava, sugarcane or sugar beet pulp, all of them are compostable, but this process is only considered “composted” The material breaks down into carbon dioxide, water, and biomass.
3D printing waste happens –

when sometimes layers aren’t sticking together properly in mid-print and depending on the model’s geometry it might cause a failure.
This could be because you’re 3D printing at a temperature that’s a bit too low.
Precaution-

Increase the print temperature slightly and ensure those layers fuse into each other.
In 3D printing, two most common filaments to print with are ABS plastic, PLA, polyamide (nylon), glass filled polyamide, stereolithography materials (epoxy resins), silver, titanium, steel, wax, photopolymers, and polycarbonate.
3D printing uses sustainable manufacturing method. Because it reduces waste.
Later its applications range from medical devices to aerospace — and possibly even drinking water.
ABS – is a thermoplastic that is great for 3D printing because of its strength and durability. This material is not biodegradable or compostable but can be recycled.
ABS (Acrylonitrile Butadiene Styrene), which Lego is made from, is a safe plastic. BabyBjorn also uses ABS – it’s BPA free. Plastics made from corn starch resin are lumped into the #7 category, and these are BPA free too.
Nylon –  is BPA free, and it’s a #7.
These numbers are for which plastics are healthier for you and more easily recyclable?

4 Ways to Recycle Failed 3D Prints

What do the numbers on plastics mean?

#1 plastics: PET or PETE (polyethylene terephthalate)(Is it safe? -No)
#2 plastics: HDPE (high-density polyethylene)(Is it safe?- YES)

#3 plastics: PVC (polyvinyl chloride or plasticized polyvinyl chloride)(Is it safe?- NO)

#4 plastics: LDPE (low-density polyethylene)(Is it safe?-YES)

#5 plastics: PP (polypropylene)(Is it safe?- YES)

#6 plastics: PS (polystyrene)(Is it safe?-NO)

#7 plastics: other (all other plastics, including acrylic and nylon)(Is it safe?- NOT SURE)

If you want to reuse any material

Use precautions-

can re-heat the material to use it again in a filament recycler.
If we like to do some craftwork, get a ‘ProtoCycler’ and make your filament.

ProtoCycler+
ReDeTec Protocycler – OMG it works!

This kind recycler will smash failed prints into smaller pieces, melt them down, and force the liquid plastic through an opening.
