Environmental remediation and hazardous waste treatment: first results from the collaboration between Directa Plus and setcar

17 December 2014

The goal is to test on field Graphene Plus, a range of graphene-based material produced by Directa Plus for water, soil and air treatment in case of organic pollutants’ contamination. Excellent results were obtained with Grafysorber™ in removing hydrocarbons from a contaminated water basin in Romania.

Lomazzo, December 17th, 2014 – Graphene Plus materials have an amazing capacity for adsorbing organic pollutants such as hydrocarbons from water, soils and air. Directa Plus has already certified the removal capacity of Graphene Plus for floating oils in water and has obtained the approval of the Italian Environmental Ministry for the use these products in oil spills clean-up activities. Graphene Plus is also object of GEnIuS (Graphene Eco Innovative Sorbent), a Directa Plus’ project co-founded by European Union within the Eco-Innovation initiative. The project aims to launch into real markets an innovative solution for water treatment based on graphene.

Directa Plus has found in SetCar – a Romanian company with fourteen years of activity in decontamination and disposal of hazardous waste – an ideal partner for testing environmental applications of Graphene Plus materials, especially in environmental remediation.

Since summer 2014, SetCar has tested on laboratory scale Graphene Plus materials as adsorbents for different type of organic pollutants. The most impressive laboratory results have been obtained with Grafysorber™ and have encouraged pilot test in hydrocarbons removal from contaminated waters.

The first treatment project started on 14th October, 2014, inside a Romanian former refinery site, containing a basin with about 16 500 m3 of water contaminated with petroleum hydrocarbons. The initial hydrocarbons concentration in water was about 56 ppm (3 drops of oil inside 1 litre of water), which means more than 1 tonne of pollutants that must be removed. The hydrocarbons maximum concentration necessary for the discharge of treated water into superficial aquatic ecosystems is 5 ppm.

“5 g/m3 of Grafysorber™ were able to bring the hydrocarbons concentration down to 1 ppm or lower and in only 10 minutes of contacts with the contaminated water! – says Eng. Covaci Melchisedec, Technical Manager of SetCar SA – We worked with a flow rate of 16 m3/h (daily flow rate of 360 -390 m3) in 2 consecutive batches of 4 m3. The total quantity of Grafysorber™ used in this project, which is now concluded, was 80 kg. In next projects, we have planned to implement the productivity of our treatment plant for low concentration hydrocarbons removal till 50 m3/h.”

Giulio Cesareo, President and CEO of Directa Plus shows his satisfaction for this collaboration and says “Our company needs partners such as SetCar SA. Setcar SA has a solid experience in decontamination field but, at the same time, a consolidate team of more than 50 engineers. Thanks to SetCar pilot test we obtained the real evidence that Grafysorber™ is an effective solution for decontamination of water containing hydrocarbons at low concentration”.

The Commercial Director of SetCar SA, Sandu Balan adds “We want to explore Graphene Plus potentiality in removing different type of pollutants from real contaminated water, soils and air and use it in other international projects of decontamination”.
