Safe utilization of sewage sludge on agricultural land using torrefaction technology

Description

Fertiliser production using sewage sludge.

Sector

A1.2Growing of perennial crops

Needs/ Problem statement

Use of sewage sludge as a valuable waste raw material in agriculture.

Objective

Treatment of sewage sludge by torefaction and pyrolysis and production of fertilizer that is storable, odorless, does not bind air moisture and its carbon is not microbially degraded after application to the soil.
