How do we define ecological materials ?
The definition of ecological materials is quite complex. The level of environmental-friendly features of a material is the resultant of many parameters ; in any case, local factors ( both environmental and socio-economic ) are of crucial importance.
The first criterion regards the environmental repercussions emanating from the excavation of the material or the raw material used for its production as well as from the material’s processing. Each time, environmental repercussions are multiple and relate to the contamination and pollution caused to the atmosphere, soil, subsoil, to the quantities of rare or irreplaceable natural resources absorbed, to the quantities of non-assimilated, non-recyclable or toxic building waste material produced and, finally, to the repercussions in the natural environment.
The second criterion regards the overall imbedded or ‘grey energy’ of the material, namely the energy required for its disposal, transfer and processing. Transferring a highly ecological material from the four corners of the world can eventually have a negative energy and economic balance.
A third criterion regards the release of pollutants hazardous to health and their toxic effects, both during their use as well as during their burning or destruction.
Finally, the expected life span of a material and the opportunity to reuse, recycle or return raw materials to the natural ground with the minimum possible loss are of vital importance.
KEBE promotes solutions that support ecological building and the so – called ” green building ” with innovative building materials, without aggravating the environment during production, since optimum counter-pollution techniques are implemented. The said products include the minimum possible energy due to their production and transfer processes, are controlled as to their toxicity, have a long life span and are recyclable.
