Does PLA go in the recycling bin? Buyers must Know

The short answer is no, PLA does not go in the recycling bin. PLA, or polylactic acid, is a bioplastic made from plant-based materials that is commonly used for 3D printing. PLA is biodegradable, but not recyclable in the conventional sense. PLA has a different melting point and chemical composition than other plastics, so it cannot be mixed with them in the recycling process. PLA also requires specific conditions to break down, such as high heat and humidity, which are not present in most landfills or compost facilities. Therefore, PLA should not be thrown away or put in the recycling bin, as it will end up as waste and harm the environment.

What are the alternatives to recycling PLA?

If you have PLA waste from your 3D printing projects, you may wonder what you can do with it instead of recycling it. Here are some possible alternatives that are more eco-friendly and creative:

  • Reuse PLA: You can reuse PLA for other purposes, such as making art, crafts, or tools. You can also melt PLA and reshape it into new objects, such as beads, buttons, or jewelry. You can use a heat gun, a hot air oven, or a filament extruder to melt and mold PLA. However, be careful not to overheat PLA, as it may release harmful fumes or lose its properties.
  • Compost PLA: You can compost PLA in your own backyard or in a commercial facility that accepts PLA. Composting PLA requires high temperatures (around 140°F) and humidity, as well as microorganisms that can digest PLA. You can use a compost tumbler, a compost bin, or a compost pile to create these conditions. You can also add other organic materials, such as food scraps, leaves, or grass clippings, to speed up the process. Composting PLA can take several months to a year, depending on the size and shape of the PLA pieces. You can use the resulting compost to fertilize your plants or garden.
  • Recycle PLA with a specialized service: You can recycle PLA with a specialized service that can handle PLA separately from other plastics. There are some companies that offer PLA recycling services, such as RePLAy 3D, Filabot, or 3D Fuel. These companies can collect, clean, and process PLA waste and turn it into new filament or products. You can either send your PLA waste to them or buy their recycled filament for your 3D printing needs.

Why is PLA recycling important?

PLA recycling is important for several reasons. First, PLA recycling can reduce the environmental impact of 3D printing, which is a growing industry that consumes a lot of plastic. PLA recycling can save energy, resources, and emissions that would otherwise be used to produce new plastic. PLA recycling can also prevent PLA waste from ending up in landfills or oceans, where it can harm wildlife and ecosystems. PLA recycling can also promote a circular economy, where materials are reused and repurposed instead of discarded.

Second, PLA recycling can benefit 3D printing enthusiasts and professionals, who can save money, time, and space by reusing their PLA waste. PLA recycling can also enhance the quality and variety of 3D printing materials, as recycled PLA can have different colors, textures, and properties than virgin PLA. PLA recycling can also foster creativity and innovation, as 3D printers can experiment with new designs and applications using recycled PLA.

Conclusion

PLA is a bioplastic that is widely used for 3D printing, but it is not recyclable in the conventional sense. PLA does not go in the recycling bin, as it will contaminate other plastics and end up as waste. PLA should be reused, composted, or recycled with a specialized service instead. PLA recycling is important for the environment, the 3D printing industry, and the 3D printing community. PLA recycling can reduce waste, save resources, and create new opportunities for 3D printing.
