Abstract
Description
This review aims to summarize research findings and
provide an up-to-date assessment of the current state of knowl-
edge on the environmental safety of digestate, including its effects
on soil, crop yields and animal health. Topics covered include the
potential benefits and drawbacks of using digestate as a fertilizer.
In recent years, the biogas industry in Europe has experienced
significant growth. Many countries are actively promoting bio-
gas production as a means to reduce greenhouse gas emissions
and achieve renewable energy targets. As a result, there has been
a corresponding increase in the production of digestate remain-
ing after the anaerobic digestion of organic waste. Digestate is
a source of growing concern due to its potential adverse effects
on the environment, specifically concerning soil quality and the
risk of nutrient runoff. A number of studies have been conducted
in European countries to assess the safety of digestate for the en-
vironment and identify ways to reduce its negative impact.
