Description

Compression molding of a composition comprising a pine bark and a method for producing the same {A COMPRESSION-MOLDED MATERIAL OF COMPOSITION COMPRISING PINE NUT SHELL AND MANUFACTURING METHOD THEREOF}

The present invention relates to a compression molded product of a composition comprising a pine bark and a method for producing the same, and more particularly, by producing a compression molded product containing an organic solid raw material without using a binder, a calorific value compared to conventional wood pellets The present invention relates to a compression molded product of a composition comprising a pine bark that can be used significantly and eco-friendly without causing any environmental problems since it significantly increases, lowers ash content and generates little harmful substances during combustion.

Pine nut is a fruit of pine tree, and it is known as a food of firewood or fresh food since ancient times. It is one of the nuts loved by many people due to its rich nutrition and savory taste. According to the Forest Service statistics, pine nuts produced 7,085,919 kg of the total domestic cultivated area of about 915,230 ha in 2004, and pine nuts produced in Hongcheon County was 3,860,400 kg, accounting for about half of domestic pine production. However, pine nuts are only used for food after harvest. Therefore, by-products other than pine kernels are discarded as they are, and left as an environmental pollution source, and they are used as some firewood as they are, but the degree is insignificant.

Meanwhile, fossil fuels such as petroleum and coal, which have limited resource reserves, are becoming increasingly depleted. The use of such fossil fuels can cause global warming problems as well as human health hazards caused by the gases emitted as fuels burn. It has a lot of influence on the cause, causing global environmental problems.

Accordingly, in accordance with the Kyoto Protocol established to prevent global warming, we are spurring the development of clean alternative energy that is eco-friendly in each country. Moreover, Korea has finalized the highest level of voluntary reductions among international recommendations, aiming to reduce greenhouse gas emissions by 4% by 2020, and has legislated the Renewable Energy Mandatory Use System (RPS). However, bioalcohols, biodiesel, etc., which have been developed so far, are expensive compared to the existing fossil fuels, and thus have limited utility.

In addition, wood pellets used as alternative energy have low thermal efficiency and low commercial value due to high manufacturing costs. Accordingly, in order to lower manufacturing costs, waste furniture and construction wastes are mixed. In this case, the manufactured pellets generate harmful gases due to the waste furniture and construction wastes, which may cause environmental problems, and camping. Roasted charcoal, which is mainly used as a fire, has a high manufacturing cost and a low thermal efficiency.

In addition to the alternative energy suggested above, high-pressure moldings capable of supplying fuel in a uniform form have been recently spotlighted as a new alternative energy. However, in general, the addition of chemical additives such as binders, combustors, and complexing agents is essential for the preparation of the high-pressure molding. A binder is a substance added to increase the strength by imparting elasticity and tack to powder formation. However, molding through the use of chemical additives such as binders, combustors and complexing agents may cause the collapse or differentiation of tissues due to carbonization of the adhesive under conditions such as high temperature and high pressure. There is a fear of generating a substance.

Accordingly, the present inventors completed the present invention by confirming that the high-pressure molded article manufactured without using a chemical additive such as a binder while utilizing a pine bark treated as waste has excellent fuel efficiency.
