Traditional paints contain highly toxic substances such as solvents, pigments and other compounds. The pigments are generally made with latex resins, natural oils with volatile organic compounds, which affect the atmosphere and human health by attacking the respiratory tract, skin, eyes and other body areas.
Some time ago, there have begun to manufacture eco-friendly paints that do not use solvents as a means but water, and whose pigments are water soluble or water-based. Their results are not as traditional paints, but their toxicity is much lower.
The application form is also important paints, brushes, rollers and brushes produce no pollution, unlike guns or spray paint.
One of the most polluting of all traditional paintings is their waste processing and disposal is not recommended in the drains, but should be disposed of in specialized places in receiving this type of toxic waste. Nor draining into the ground as they can reach the webs of water and contaminate groundwater.
It is advisable to avoid packaging paint are not completely closed, so that its toxic vapors do not escape into the atmosphere.
The paintings are considered highly polluting in terms of processing waste. So much so that in some countries there is a special collection of these wastes to minimize their danger to the environment and public health. A good way to reduce home the toxicity of these wastes is simply buying less, and adjusting to the amount actually going to need. The less paint on the better.
Vegetable and mineral paints:
The ecological paints must be made of renewable raw materials, nor should it be environmental pollution in the manufacturing process or in the application and disposal. The paintings vegetables and minerals are 100% organic and non-polluting and their raw materials come from renewable sources.
In developing these natural paints are used: resin, rhubarb, mulberry latex, chamomile, birch, indigo, linen, oils, waxes, from different parts of the plant (leaves, fibers, flowers, roots, bark, etc.) These compounds are combined with other non-toxic biodegradable substances (water, earth, talc) to offer products similar to conventional paints.
The raw materials come from renewable crops or recycling. Furthermore, some of the components occur in the vicinity of the plants, thereby reducing the energy cost of transportation.
Inorganic pigments can also be used mineral origin which agglutinates with liquid potassium silicate and silica sol. This system is known from the late nineteenth century.
