Lubber tree is known to be difficult to make good use of trunks with less than 20% of utility rate. Meanwhile, palm tree has been totally unusable and wasted as “troublesome creature” either by burying or burying in the ground. It goes without saying that effective usage of limited forest resource is directly associated with the global level of environmental issue. Therefore, in order to, (1)increase utility rate (yield) of trees that are cut, elimination waste, and (2)rejuvenate many of unusable trees to become construction materials of furniture, EDS has been developed as a technology to improve the quality of wood. On the basis of “smoking with heat theory” EDS is a technology to resuscitate thinned-out, low quality, unusable or fast growing trees as marketable wood with high quality. The heat process under the computer program reduces the level of internal (growing) stress to minimize wood's defects such as bending, cracking, warping, shrinking, corroding, resin seepage, etc. Throughout the process, no chemical agents ar used; and scrap pieces of wood from construction sites or forests are used for a heating source instead of fossil fuels. Thus, EDS attaches a great importance to the environmental issue as a resource recycling technology.

Sealant manufacture is grappling with the scrapping quantity reduction of the package container as a countermeasure to the environmental problem. A metal can is being used for the container of two-component sealant from the durability, working efficiency, stable storage, good conveyance and so on. Then it is laid in the landfill site for stable industrial wastes after the containers are used. New container manufactured by the film laminate in place of the metal container was developed to reduce this industrial waste. New container secured the same working efficiency as the metal can by using a blender. And it is compressed by the capacity of 1⁄6 easily and safely. Then maximum 37% of the scrapping capacity of the new container decreased in comparison with metal can. When it is kept and carried, it is compact. From now on, a recycling system will be built, and it will work for more decrease in environment load.
