Biological recycling of bio-waste and compost utilization from a life cycle perspective
نویسندگان
چکیده
In order to set a reference inventory data, an extensive literature search on compost production and compost utilization has been performed. The aim is to define carbon and energy footprint of bio-waste recycling and compost utilization. The available data suggest that when bio-waste is properly collected and recycled (through composting or anaerobic digestion) and a high quality compost is produced and used, valuable environmental benefits can be achieved. In particular, the recycling of 1 tonne bio-waste generates GHG emissions that range from -0.3 up to ~0.1 tonne CO2 equivalents (i.e. eq.), whereas the consumption of fossil resources ranges from -4.4 up to 0.5 GJ eq. depending on the bio-waste recycling technology and compost utilization considered.

متن کاملOrganic Waste for Compost and Biochar in the EU:Mobilizing the Potential
While several EU member states have working compost markets, only about one third of the bio-waste, around 35 Mio tons is used to produce compost, and to some degree, biogas. The major part is still incinerated or landfilled together with other waste. This paper proposes the improvement of existing and the creation of new compost markets based on the integration of biochar and the implementatio...
