BIOMIMIC – on the way to a sustainable metal supply

With the escalating demand of metals in an increasing global population, Europe is confronted with the challenge to secure a sustainable metal supply. Lack of cost effective technology to extract heavy metals from hazardous, metal-rich fly ash collected in complex municipal solid waste streams has escalated societal challenges due to environmental as well as monetary costs. Fly ash could instead be a resource for metal recovery. Another challenging waste stream is hazardous waste from alumina production.

The BIOMIMIC project addresses key problem areas of complex waste processing. The primary objective is to create and validate new biotechnological metallurgical methods that have the potential to concentrate metals in dilute solutions while leaving the residue free from toxic substances. It will be achieved through technology development of biotechnological methods pertaining to treatment of waste streams.

The project is coordinated by RISE and funded by Vinnova (Sweden), Bundesministerium fur Bildung und Forschung (Germany) and Geological Survey (Ireland).

Nordic BioEngineering AB is one partner in this project, and our role is to be work package leader for the development of biotechnology trials in lab, based on our microbial products and of sulfate reducing bacteria.

The objective of the work package is to increase technology readiness level of sulfate bioreduction and metal precipitation of the relevant metal solution from waste incinerations plant from three to five by validating the technology in a relevant environment.

The objective is to develop a microbial consortia, use innovative reactor design and use readily available waste carbon source to reduce the cost. Validation in lab / pilot scale mimicking industrial conditions is also included in this work.

Pilot tests for new bioremediation method for PAH-contaminated soil

We are doing pilot tests with Ragn-Sells AB in Häradsudden, Norrköping, to develop a modular and mobile solution for treatment of PAH-contaminated soil, by using our microbial products with Archaea.

The aim of the project is to develop an innovative and cost-efficient biological treatment technology that is fully based on natural degradation processes of contaminants and to stimulate this method through mixture with renewable resources (e.g. waste from the forestry and pulp industry).

Initial results have shown that breakdown of polycyclic aromatic hydrocarbon (PAH) is between 40-60% in the contaminated soils. Further investigations have to be done on the mixing process and to optimize the blending facility as well as to ensure the efficiency and compare the cost of alternative treatment options in large scale.

Remediation time to reach an acceptable level of PAH so that the masses can be put on landfill for non-hazardous waste

The pilot tests have been financed by Vinnova through the program Innovative startups.

Developing a smart oil spill absorbent with KTH

Together with KTH, Nordic BioEngineering is developing a new and innovative absorbent made from biodegradable compounds.

Everyday oil spills occur from e.g. trucks, cranes, boats, machines, cars and storage tanks. All these small spills adds up to a significant environmental impact as well as posing a health hazard to personnel due to exposures to harmful substances. When spills happen you need quick access to decontamination and protective equipment. It is both time consuming and costly to handle and dispose of this kind of oil and chemical spills in a safe and appropriate way.

Today, market is dominated by absorbents made from minerals or synthetic material. The absorbent is used to cover the spill. In best case, the absorbent is collected and kept separated as hazardous waste and then sent to an industrial site for destruction or deposit on landfill.

Based on our experience in the field, we know that the absorbent is very often left in the environment and not collected or swept up.Nordic BioENginnerging has been working on a new solution to this problem since 2015. We are devekopping a new oil spill response method. Our method is based on treating the spill on the site with a product that combines a new kind of absorbent and our microbial products.

The project has been financed by Vinnova, Region Västmanland and FoU Västmanland.

Bioremediation of rock cavern in Stockholm Royal Seaport

Nordic BioEngineering AB is part of project that clean up a rock cavern of 90 000 cubic meters polluted water in Stockholm Royal Seaport. This is the first time a bioremediation method using Archaea in Sweden and the results has been very successful since the remediation started in the early spring 2017.

The remediation uses both mechanically and biologically methods. Responsible for the remediation is Fortum Värme and Stockholm Parking.

The mechanical part of the purification simply consists of pumping water from the mountain, cleaning it in a bubble chamber, and then releasing the return water to the mountain room. New water is pumped up, purified, and then the process continues until the water is relatively clean.

To get the rock cavern and the mountain totally remediated, a biological treatment is necessary as a final remediation step. The bioremediation is done with the help of our microbial products containing Archaea. The microbes break down the hydrocarbons in several stages and the remains is harmless substances such as water, carbon dioxide and biomass.

The bioremediation stage consists of a sedimentation container that is fitted with air nozzles to oxygenate the water. Archaea and nutrients is added depending on the level of contaminant. Contaminated water is purified with a flow of 3000 liters per hour in each container. The efficiency of cleaning is 100%, results from analysis of the water is below the detection limit for naphtha (that is below 10 µg/l). The purified water is returned to the rock caverns. In this way, this biodegradation can continue in the mountain until the remaining oxygen and nutrients are consumed by the Archaea.
