Identification of external risk factors: on the example of production of fertilisers based on digestate

Abstract

In the era of renewable energy development, one of the most important problems is the utilisation of residues of production of the so-called clean energy. In the case of biogas plants, the problem is the utilisation of waste after the anaerobic methane fermentation process of the organic substrate. One of the ways to use it is to produce organic and mineral fertilisers. However, the fertiliser plant may be exposed to a number of threats that may prevent its functioning. To avoid this, the factors that carry the risk need to be identified. The purpose of the article is to identify external risk factors for a fertiliser plant based on digestate. The following types of risk were identified as a result of the research: risk of supplying fertiliser components of inadequate quality; risk of non-compliance with deadlines for the delivery of raw materials or their total absence; risk of the presence of eggs of parasites and pathogenic bacteria in fertiliser; price risk; cyclical risk; risk of competition; currency, credit and interest rate risk.
