1. Is your company based only in Italy?

No, we have technical and commercial offices in Italy (Brescia and Rome) but we produce RECAM^® in the Czech Republic (Rudna, near Prague) where we have also our laboratory area for research and development and pilot tests for water and wastewater treatment. top.

2. Is SA Envitech a private company?

Yes, funded in 2007 with a sole shareholder. top.

3. Are you interested in venture capital or new private or public shareholders?

No, but we are always open to evaluate proposals for lincesee agreements, and we are interested in leveraging strategic alliances to maximise revenue streams. top.

4. How many people work in SA Envitech?

The staff in Italy is of 23 people with companies that have partnership with SA Envitech and 5 in Czech Republic top.

5. What are SA Envitech’s main objectives for the next 2 years?

SA Envitech’s efforts are now focused into the production and improvement of RECAM^®. We are confident of RECAM^®’s potential to become the most reliable and efficient product for water, wastewater treatment, gas tretment and soil remediation in the next two years. The mission of SA Envitech is to develop new materials and technologies for environmental applications and we are currently developing a new product complementary to RECAM^® that will be introduced to the market in 2012. top.

6. What are the main points of your business model?

Our business model is mainly based on these primary goals:

• become a worldwide leader in the development and production of innovative materials and new technologies for environmental applications
• extend our innovations into foreign markets through partnerships and license agreements with leading companies.
• manage and enhance Customer Relationship
• to be accredited in the market as Best in Class Solution Provider.
• predict and meet future market requirements through R&D. top.

7. Is RECAM^® a new activated carbon material?

Absolutely not, RECAM^® is a mesoporous nanostructured carbon material that acts differently in terms of contaminant removal when compared to activated carbons, and which has a different kinetic and porous structure. But the most important point is that RECAM^® has proved to be much more efficient than activated carbon, resins and other filtration materials for a wide range of contaminants. top.

8. Which products on the market are similar to RECAM^®?

There are no other products that may be compared to and compete with RECAM^®. Carbon materials that may have few elements in common with RECAM® are all mesoporous carbon materials, but the main difference is the internal nanostructure of the carbon. top.

9. Does RECAM^® contain chemicals?

Absolutely not. RECAM^® is a pure carbon material, this may be verified by anyone through a qualified laboratory. top.

10. How much is the cost of RECAM^®?

The cost of RECAM^® depends from the type of RECAM^® that you need. RECAM^® RE.40 is the only type of RECAM^® that we sell in its original form since it is used to recover hydrocarbons. However, the cost is significantly lower than other products present into the market if you consider the profit obtained in terms of energy production (when the material containing the heavy hydrocarbons recovered is burnt) and in terms of oil recovery (when the material is pressed to recuperate the oil spilt). For other types of RECAM^® we sell filters together with water and wastewater treatment service. If you are interested in knowing the cost of such filters and plants, please contact us and send us further details (ie. volume and contaminants) in order to formulate a proposal. top.

11. Why are treatment processes with RECAM^® different from traditional technologies?

All processes do not produce sludge and any other kind of waste, they do not require chemicals (only in some cases for pH corrections), the plant technology required is very simple therefore the financial investment for the treatment plant significantly lower. But, the most important aspect is that the efficiency of treatment with RECAM^® is considerably higher for a wider spectrum of contaminants. top.

12. Is RECAM^® used only for filtration processes?

No, filtration with RECAM^® may be applied for many cases of water contamination, in particular for groundwater treatment, drinking water treatment and many industrial applications, however, when the organic content is quite high (i.e. COD > 2000 mg/l) it is better to employ advanced oxidation processes that use RECAM^® as described on our website. top.

13. Which are the main contaminants that may be removed by filtration with RECAM^®?

The filtration process using RECAM^® has been successfully applied to a series of common recalcitrant compounds, such as: benzene, ethylbenzene, toluene, styrene, m-xylene, o-xylene, p-xylene, fluoranthene, fluorine, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(g,h,i)perylene, chrysene, dibenzo(a,h)anthracene, indeno(1,2,3-cd)pyrene, pyrene, naphthalene, acenaphthylene, acenaphthene, indane, indene, 1-methylnaphthalene, 2-methylnaphthalene, biphenyl, phenols, heavy hydrocarbons, methanol, chloromethanes, trichloromethane, vinyl chloride, 1,2-dichloroethane, 1,1-dichloroethane, 1,2-dichloroethylene, 1,2-dichloropropane, tetrachloroethylene, arsenic, cadmium, chromium VI, iron, manganese, copper, zinc, boron, COD, BOD₅, anionic surfactants, cationic surfactants, MTBE, atrazine. There are many other contaminants that RECAM^® may remove but have not been tested yet, therefore the list of contaminants which RECAM^® removes efficiently is increasing month by month. top.

14. What kind of wastewater may be treated with the advanced oxidation process that uses RECAM^®?

Generally there are no technical limitations to an kind of wastewater, however, based on our experience we found that the advanced oxidation process with RECAM^® is particularly interesting to apply, in terms of efficiency and economical benefits, in the following fields: landfill leachate water treatment, industrial water with recalcitrant compounds, tannery wastewater, paper industry wastewater and all cases where conventional technologies have encountered technical limitations. top.

15. Is it possible to integrate the technologies with RECAM^® into existing treatment plants?

Absolutely yes. In some cases it can be a smart solution to integrate RECAM^® processes into existing plants, for the removal of specific contaminants, thus eliminating the requirement to invest in a new plant. top.

16. What is the duration of RECAM^® filters?

The lifetime of RECAM^® filters depends, clearly, on the type of contaminants, their mass balance and the final goal of treatment. In most of cases, the duration of filters is in the range of a few months to one year. top.

17. Once used, how is the RECAM^® filter disposed of?

Our company provides for filter replacement, directly from the site where the treatment plant is installed, without producing any kind of waste on site. top.

18. Is it possible to regenerate RECAM^®?

It is possible for some kind of contaminants, as for example hydrocarbons. SA Envitech is currently developing solutions for regenerating RECAM^® retaining a wide range of contaminants. top.

19. What contaminants cannot be treated with RECAM^®?

Generally filtration with RECAM^® is not effective with all salts, such as chlorine, sulfates, calcium, magnesium etc. top.

20. What are the main benefits of using RECAM^® for drinking water applications?

RECAM^® removes more than 99.9% of recalcitrant contaminants such as boron, hexavalent chromium, MTBE, PCB, phytochemicals, arsenic, cyanide, light and heavy hydrocarbons, chlorinated solvents, surfactants, iron and manganese. The high bactericidal and bacteriostatic power of RECAM^® also provides for excellent quality standards for water purification, without altering the water’s saline content in any way, with evident benefits when compared to activated carbon, resins or reverse osmosis. top.

21. If I use Recam^®, do I still need to put chlorine or other disinfectants in the water?

No, RECAM^® is a bacteriological and bacteriostatic material. top.

22. What quantity of hydrocarbons can RECAM^® absorb?

One gr. of RECAM^® can absorb 85–90 gr of hydrocarbons, about 5 times more than the most competitive product currently available on the market. top.

23. Once RECAM^® has absorbed hydrocarbons, how can the oil be recovered?

It is possible to recover about 90% of the heavy hydrocarbons englobed inside the nanostructure of RECAM^® just pressing the material. top.
