It suits here to emphasize that, for us, leftovers and wastes are not taken
as garbage or disposable materials, but as raw materials of high value
For 40 years Prof. Mymrin has worked in the field of study of reuse of industrial
residues as raw materials in order to help enterprises which are facing environmental
problems. He has developed methods (compositions and technologies) for manufacturing
of materials such as: ceramic, glass-ceramic, refractory, concrete, plasters,
thermal/acoustic insulators, bases for roads, airports and of municipal and
industrial landfills, cores of dams and new varieties of fuels having high calorific
value. The developed methods allow the collection of spilled oil with recovery
of grounds, the cleaning of oil layer in tank-ships and of other petroleum materials.
Objectives of the researches:
- To help the enterprises to face environmental problems.
- To use as much quantity of industrial residues as possible.
- To study the possibility of tying heavy metals to the process of industrial
residues usage.
- To develop new materials (mainly those for construction) which are favorable
to the Environment and usable in the economical sense with sufficient properties.
- To investigate physical-chemical processes of new materials structure formation
in order to
increase its most valuable properties. Now we can use the following industrial
residues as raw materials:
- Iron and steel residues:
- Wastes of Machine Construction:
- Municipal wastes:
- Residues of the Construction and Demolition:
- Residues of Production and reuse of paper, cardboard and cellulose:
- Residues of Mining and Preparation:
- Wastes from Petrochemical Industries;
- Energetic Residues:
- Chemical industry wastes:
- Agricultural wastes: Based on this knowledge we can develop uses for other
residues and wastes. All developed products contain much less amount of lixiviation
of heavy metals than the
Brazilian and international rules standards. A very low cost of raw materials
(industrial residues), ensuring a high economical effect of production of these
materials.
- To develop new or to adapt current technologies of new material production
in the level of pilot plants.
The greatest benefits
Environmental
- Complete liquidation of landfills of industrial residues for the use of
wastes as raw material;
- Chemical connection of all heavy metals in the developed materials up to
level of lixiviation and solubilization, according to the demands of Brazilian
and international standard regulation.
Economical
- Significant reduction of the payments of taxes and environmental fines.
- A very low cost of raw materials (industrial residues) ensuring a low cost
of materials produced and high economical effect.
- Possibility of price decrease of materials in the market.
Social
- For the production of new materials developed, it’s necessary to
create a new chain of enterprises with generation of new job openings.
- Cleaning of industrial landfills increases the quality of life of the population
of industrial areas.
Educative
- To prepare new generation of Brazilian scientists to continue inquiries
and to work in the enterprises in the field of industrial residues with the
benefits pointed out above.
- To increase the level of environmental education of the population through
courses, lectures, classrooms and other forms of dissemination of practical
knowledge in the field of sanitary and environmental engineering.
- To prepare and to execute the education of students with subjects of Advanced
Topics “Materials of Industrial Residues” in the level of Master’s
and Doctorate degrees on basis of researches and of international scientific
and technological literature.
