Sustainably sourced wood: Fenex sources wood material from suppliers who have chain-of-custody certification by PEFC and FSC.A common hesitation about using wood products is based on trees cut down for producing these products. While part of the trees in the world is really based on the forests under threat, another part is product of rational economical forestry. All wood material used for Fenex products is the result of the second type of forestry and has the certificates of PEFC and FSC as an evidence of this fact. Use of these trees is supported by the national policies of the producer countries.
In 1992, United Nations introduced maintainable forest management as a global requirement at the Earth Summit in Rio de Janeiro. When the age of a forest passes 40 years, timbers can be collected. Because, the growing rate of a tree is not usually economical after this age. Since trees convert carbon dioxide to oxygen when they are growing up, the ones that are most beneficial for the nature are the young, growing trees. Therefore, cultivation based on cutting old trees and planting new ones is more beneficial for the nature. In Germany, over two million forest owners who use the forests which are founded by their forefathers 100 or more years ago, work in a a kind of inter-generation dependency.
While the consumption of artificial products support their production, the consumption of economically maintained forest products support this kind of forestry and helps protecting the environment.
Wood is produced by water, sun, soil and air; not by toxic chemicals.
Wood is the only construction material that is reproduced by itself. If wood is used, limited raw materials on earth are not consumed. Wood is reproduced by solar energy. When a tree is growing up, it absorbs carbon dioxide which is one of the greenhouse gases and decreases the amount of this gas in the atmosphere. Trees absorb approximately 1.9 tons of carbon dioxide by photosynthesis, produce oxygen and stock 500 kg carbon for producing 1 ton of log. Each year, 1 hectare of forest removes 50 tons of suspending dust. Roots of trees hold soil against erosion especially on inclined grounds.
When compared to other construction materials, preparing and processing wood is accomplished by minor energy consumption. For example, production of a steel profile that is 3 m long, costs 561 kWh energy, and this value is just 60 kWh for a wood profile. Besides, wooden windows can be cleaned using only water. While forests eliminate CO2 by converting it to wood, they produce pure oxygen as "waste gases". This is just the opposite of other processes. CO2 is released only when wood is burned, and during this time electrical or thermal energy is produced. On the contrary, recycling PVC is difficult and costly because of the scarcity and distance of necessary plants.
Wood industry has considerable contribution to local economy as well as the environment. In Germany, wood working sector creates more employment areas than automotive sector and provides more turnover than electronics. Approximately 20,000 people are employed solely in wood carpentry industry, and an important part of the total window demand is met with wooden windows by production of 2.9 million wooden windows per year.
Processing wood creates almost zero waste. All by-products and wastes are valuable raw materials for various uses. For example, all wastes and sawdust are used in Fenex to provide the heat source of plant. Wood is a part of the natural cycle and destroyed or re-utilized easily. Since wood products are painted with water based and environment-friendly paints in Fenex, these paints are dissolved easily in nature. Disposal of PVC and fiber board wastes, on the other hand, is a big environmental problem.
Because of all these reasons, there is no law limiting the use of wood except the kinds under threat in any country. However, 256 different laws in Germany prohibit or bring stringent limitations to the use of PVC.
