As the statistics predicts increasing the world population from the current number of 7.8 billions to 9.8 billions in the year 2050, the amount of bio-waste generated from human activities would also increase, causing more pollution problems to the environment. Environmental protection by reducing waste is an important global issue. Inadequate waste management leads to climate change and air pollution, which directly affects many ecosystems and species. According to statistics, up to 50% of municipal solid waste is biodegradable, which plays an important role in recycling and the circular economy. Currently, around the world biodegradable waste in landfills is the main factor for the generation of the greenhouse gas methane and the main environmental threat, which accounted for some 5-6 percent of total greenhouse gas emissions in the world in 2010. Thus, without stringent measures to reduce the bio-waste, methane emissions are expected to increase approximately 25 percent until 2050. Bio-waste is recyclable and hence must be used smartly in order to trim down the greenhouse emissions that come from landfills. The recycling rate of municipal bio-waste is an important indicator, but it cannot be measured on the basis of reliable data given that part of the biowaste remains an integral part of mixed municipal waste. Recycling is the process of organic waste management where they are recycled or converted into useful matter by different recycling methods. There are different methods of bio-waste recycling, each of which can be used for a particular group of waste to produce some form of useful organic matter. Some of the common methods are described below: animal feed, composting, anaerobic digestion, rapid thermophilic digestion, immobilized enzyme reaction. Recycling, as a part of the Circular Economy indicator set, permits to measure the progress towards a circular economy based on “waste management” concepts. This indicator is important for evaluation of importance of composting/anaerobic digestion as a contribution to circular economy objectives for municipal waste. In this context, the indicator is calculated as the ratio of composted/methanised municipal waste (in mass unit) over the total population (persons). Several studies and statistics show that, by and large share treatment of bio-waste are realizing by composting or anaerobic digestion methods. The end product from the composting or anaerobic digestionare is used as organic fertilizer or replaces peat in potting soil and plant substrates. The bio-waste recycling may also directly contribute to climate protection if the methane produced during the fermentation is used for energy production.
