The annual direct cost of corrosion estimated worldwide exceeds 1.32 trillion, which means approximately between 3 to 4% of the Gross Domestic Product (GDP) of industrialized countries. Among the different types of corrosion Microbial Influenced Corrosion (MIC) caused by fouling is estimated to be involved in at least 10% of the corrosion problems of structures reaching to 50% in the case of subterranean pipes.

Existing antifouling solutions include biocides and solutions not environmentally friendly. Latest research has begun to focus on greener replacements, but up to now, with low environmental performance and durability ratios. This fact has caused an urgent demand for greener, non-toxic or low-toxicity (green Anti-Fouling agents) and longer lasting antifouling compounds and technologies.

The main objective of the project is the development of an innovative bio-mimetic and eco-efficient environmental technology for inhibiting microbial induced corrosion (MIC) produced by bio-fouling through the integration of microorganisms in a sol-gel coating for metal surfaces of civil engineering structures in marine and terrestrial environments. The potential economic impact of the technology developed in the project could mean approximately 612 billion in direct cost.

The general objectives are expected to be achieved through the following WPs:
WP1: Microorganisms and inhibitors to be included in the sol-gel matrix
WP2: Synthesis of a sol-gel enriched matrix for corrosion inhibition
WP3: Environmental aspects of the bio-mimetic developed coating
WP4: Demonstration
WP5: Dissemination
WP6: Business models and Exploitation
WP7: Project Management

PROJECT GOALS:

BIOCORIN project aims to develop a green alternative to the coatings and solutions used up to date for MIC corrosion protection and prevention in infrastructures. The concept of the project is the identification of anti-fouling microorganisms, their later integration in a solgel coating and finally the monitoring of the coating performance, latest technologies, solutions and methods related to those fields
will be analysed.
The concept of the project is based on a biological phenomenon commonly occurring in nature for microbial population regulation. Microorganisms secrete compounds that inhibit the growth of other microorganisms due to existing antagonism between microbial populations. This behaviour will be used for inhibiting the growth of the microorganisms responsible of MIC and biofouling.

The technology will be demonstrated and validated by means of three case studies with different environmental conditions. The demonstrators have been selected on the basis of geographical criteria to evaluate the effects of different environmental conditions in anti-MIC and antifouling capabilities of the developed technology. A new demonstrator has been added with respect to the case studies foreseen in the proposal submitted to the 1st stage. This demonstrator will be carried out in the North Sea in Rotterdam (The Netherlands) by VLCI.

The particular climatic conditions and characteristics of the North Sea with respect to the Mediterranean cases studies will permit to demonstrate the replicability of the BIOCORIN solution and its adaptation to different conditions and fouling characteristics. Therefore, the following demonstrators will be carried out:

1. Marine demonstrator in the Harlingens port (Netherlands)

2. Marine demonstrators in the port of Ribeira in Galicia (Spain)

3. Terrestrial and marine demonstrator in Naples (Italy)
BIOCORIN project will identify microorganisms most suitable to counteract the fouling and MIC threats in civil infrastructures affected by these phenomena under different types of conditions.
Instead of purifying the bioactive compounds from organisms or synthesize the chemical compounds, the technology will use latent microorganisms that directly act secreting the required antifouling or anti-MIC compound when needed, once this kind of corrosion starts.

Optimum and homogenous reaction conditions will be studied for the production of BIOCORIN antifouling compounds and to design an adequate industrial fermentation process. A consistent product quality be will be aimed by minimizing microbial stress exposure and enhancing metabolic accuracy of the process.

Suitable strategies for processes and facilities will be designed by a comprehensive and detailed process characterization, identifying the most relevant process parameters that influence both product yield and quality and establishing them as scale-up parameters to be kept constant as far as possible.
