MATER-BI compostable shopping bags have an important dual purpose. Companies purchase MATER-BI resin and transform it into compostable shopping bags which are initially used like any other shopping bag for carrying groceries and products home from a store.These compostable bags have the same properties of conventional plastic.
At home, consumers use the bags to collect organic food scraps and yard trimmings. Many consumers take their groceries home from the store in compostable shopping bags and then re-use the bags to collect food scraps.
Once a bag is filled with organic waste, or once a bag has met its final use, it is collected for composting or placed in a backyard bin. Unlike conventional plastic, MATER-BI biodegrades in a composting environment. This means that microorganisms view the MATER-BI as food, and digest the bags just like they digest organic food scraps. The end product, compost, is then used to provide nutrients and humus that are used to grow new crops.
