Biowaste in the current process is defined as follows:
Biodegradable garden and park waste, food and kitchen waste from households, restaurants, caterers and retail premises, comparable waste from food processing plants, it also includes forestry or agricultural residues and manure. It does not include sewage sludge, or other biodegradable waste such as natural textiles, paper or processed wood.
The composting treatment is a process of controlled decomposition and humification of biodegradable materials under managed conditions, which is aerobic and which allows the development of temperatures suitable for mesophilic and thermophilic bacteria as a result of biologically produced heat.
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.


Compost inventory refers to open plant compost production.
The process step-by-step, from shredding to products:

1. Reception and weighing (+ storage of feedstock)

2. Shredding (depending on structure of feedstock)

3. Anaerobic digestion (AD) and solid/liquid separation

4. Rotting process, turning over, aeration and watering
5. Post-processing and conditioning
