New innovations in zero waste
Every year more than. The majority of this plastic makes it back into the biosphere, whether in landfills or natural spaces. Plastic poses a serious ecological threat because it doesn’t fully decompose,but breaks up into smaller pieces called microplastics, which can be eaten by and accumulate within wildlife. While the threat that plastic poses to the environment seems unavoidable at times, people are working hard to reduce the amount of petroleum based plastic that makes it into the biosphere. Here are four innovations that are helping to reduce our plastic waste.
Algae, an umbrella term used to describe seaweeds, kelpsand photosynthetic eukaryotes, can be used inplastics and hasbecome an
Algae will provide enough biomass to produce large quantities of this form of bioplastic as they are the fastest growing organisms powered by sunlight.
Algae also has the advantage of being able to take up carbon dioxide from the atmosphere during the growing process.
Start-ups are already beginning to use algae to create hyper-compostable single-use plastic products. Some examples of this are, a company creating single-use straws out of seaweed that can sustain over 18 hours of use and will break down at the same rate as food waste and, an edible and biodegradable water pouch made of algae.
PLA plastics
PLA plastics arebioplastics derived from renewable resourcessuch as corn starch and sugar cane.
PLA plastics areamong the most used bioplastics in the worldas they have a wide range of versatility. These plastics can be made into items from single-use cups to long-lasting medical screws.
These plastics are able to decompose into organic matter if sent to an industrial composting facility.
PLA plastics are indicated by a number seven recycling symbol. However, this does not mean they are recyclable like petroleum based plastics. Number seven PLA plastics should instead be composted or thrown away if composting is not available.
Students from Yale University discovered that Pestalotiopis microspora, a species of mushroom from Ecuador, iscapable of surviving on a strictly plastic diet.
This mushroom consumes polyurethane, the main ingredient in plastic, and turns it into organic matter.
Pestalotiopis microspora is not the only mushroom capable of plastic decomposition. Oyster mushrooms, a very common species, also has this ability.
These mushrooms can survive without oxygen, making them an ideal candidate for cleaning up landfills where oxygen is extremely limited.
Researchers are also working to createat-home recycling kitsusing these mushrooms.
Pestalotiopis microspora and oyster mushrooms are both edible, meaning at-home recycling kits would provide both a food source and a way to decompose plastics.
is a plastic bottle packed full with used pieces of plastic.
Ecobricks reduce the surface area of packed plastic to keep it from degrading into tiny microplastics.
Ecobricks are made to a certain density and can then be used as reusable building blocks to build walls, structures, green spacesand even furniture.
Some purposes of ecobricks include keeping plastic out of the biosphere in the long-term and “.”
Ecobricks only require cleaning, drying, and then packing plastic into a plastic bottle, which means they can be made by anyone! To find more information about how to ecobrick and where to drop off any ecobricksclick.
