A Greener Alternative to Conventional Biocides in the Oil Industry

Impact: Green impact, Economic impact

Description of impact

Researchers from Aalborg University and VIA University College have obtained a patent for a method to produce extract from halophytes – a type of plant that naturally grows in saltwater environments. The extract can be used to prevent microbiologically influenced corrosion (MIC), which is a major issue in offshore oil facilities. MIC occurs when pipes and equipment are attacked and degraded by sulfate-reducing bacteria (SRB). These bacteria thrive in so-called biofilms – slimy layers that protect them and make them difficult to remove. Current solutions typically rely on chemical substances (biocides), which are often toxic to the environment and ineffective against biofilms. To address this, the researchers developed a method to extract natural antimicrobial compounds from halophytes, offering a more sustainable and gentle way to combat the bacteria.

The patented method is expected to have a green impact, as it enables the production of a clean, natural, and non-toxic alternative to conventional chemical treatments. It also has an economic impact, as it may challenge existing solutions in terms of both cost and effectiveness.
