BioBags are the first 100% biodegradable alternative to plastic bags. They are made from cornstarch, vegetable oil and other renewable resources.
BioBags makes kitchen “compost bags” to store foods scraps before composting. They can also can be used to store food in the refrigerator. The advantage over plastic, is that these bags will “breath” without leaking. This allows heat and moisture to evaporate, which keeps food fresh longer. Also, unlike plastic bags, there is no risk of Biobags leaching unhealthy residues into your food.
For the garden, there is Garden Bio-Film, which is designed to protect your plantings from weeds and stimulate warmth for uniform growth, then return itself to the earth after the plantings reach maturation. The film also serves as a plant protector during frost and wind warnings.
