The first step to successful composting is the collection of the appropriate waste. Dog poop waste is often collected in plastic bags, which are bad for the environment, do not breakdown easily and are not digested by worms. Just Bio Bags are made from corn and are just as strong as plastic bags but are natural and degrade. Worms can also digest them. Dog Biobags are also available and provide a compostable and biodegradable way of collecting dog waste, which can then be more easily disposed of. The bags will biodegrade within a couple of months. They are supplied in packs of 50 black bags.
