Web tool to assess on-farm biogas-plant projects with a liquid phase process and associated to a Combined Heat and Power unit ranging approximately from 50 to 500 kW.

The simulation figures out technical and economical references. MéthaSIM holds a database with the potential methane production of over 200 products and organic wastes, and of more than 200 types of manure. It allows to calculate heat requirements in a variety of cases: drying of fermentation issue, house or greenhouse heating, etc.

The web tool also assesses the necessary equipment size (digester size, electric power of the CHP) according to the various available fermentation wastes and co-substrates. The economical result is calculated from all technical features and figures out the net present value, gross operating profit and return on investment for examples.
