Abstract
There are 25% of the wood waste will be produced during the wood processing, and most of the wood waste will eventually be used as a low value products, such as wood chips and wood fuels . How to increase the value of wood wastes and their utilization is became an important issue recently. Many printers are using raw plastic materials, make a lot of impact on environment indirectly, if we can use the bio-decomposable materials as breeding containers, it will not only beneficial to environmental protection, and can promote the future growth of seedlings.The purpose of this study is to mix polylactic acid (PLA) with wood wastes to manufacture new materials for 3D printing. The study will also analyze the processing conditions and market ability of the PLA/Wood 3D printing material. This study is also to explore corn starch biodegradable plastic mixed with wood waste to manufacture seedling container. The strength and durability properties of the test piece will be test in laboratory. and the actual planting seedlings in the field of field experiments to test their lifetime in use, the health assessment of the growth of seedlings is also be envalued. Due to social trends, more and more people are used to accompany with the animals, such as cats and dogs, in home. The need of to maintain the living environment quality for human and animal is also increasing. To the cat, the defecation, urine has a pungent odor, the traditional mineral sand or crystal sand often add extra flavor, in an attempt to cover the smell of fragrance. Wood is a porous biological material with its own, and its extract often contains anti-bacterial effects of mosquitoes, this study is to apply the wooden materials in pet litter to assess its odor absorption capacity on the pet cat urine, and further evaluation the use of the material for the common pathogens and possible parasitic fleas whether the suppression and avoidance.The overall purpose of this study is to develope high value-added products to increase the use of wood waste value, and to achieve full use of wood materials and meet the thrust of circular economy.
