초록
폐목재의 활용에 관한 특허동향 분석을 위해 한국특허정보원의 특허정보검색서비스(KIPRIS)에서 관련 키워드로 한국, 미국 및 일본의 특허 검색을 실시하여 2011년 12일 31일까지 특허 등록된 한국 77건, 미국 316건 및 일본 317건의 특허 자료를 수집하였다. 수집된 자료 중 거절, 소멸, 무효, 취하, 포기 및 폐목재와 관련이 적은 내용의 특허를 제외시키고 얻은 한국특허 71건, 미국특허 216건, 일본특허 227건에 대한 분석을 실시하였다. 또한 폐목재를 콘크리트용 경량골재로 활용하기 위한 기초 연구로서 파쇄시킨 소나무 임목부산물을 No. 8(2.4 mm)체로 쳐서 이를 통과시킨 것을
Patents in Korea, Japan and the U.S. were searched at the Korea Intellectual Property Rights Information Service (KIPRIS) of Korea Institute of Patent Information using related keywords in order to analyze the trend of patents on the usage of waste wood. Materials on a total of 77 patents in Korea, 317 patents in Japan, and 316 patents in the U.S. that had been registered as patents as of Dec. 31, 2011 were collected. Among the collected materials, the patents rejected, expired, annulled, withdrawn and waived as well as those which had little relationship with waste wood were excluded and the 71 patents in Korea, 227 patents in Japan and 216 patents in the U.S. were finally selected for analysis. In addition, the properties of the mortar which used waste wood as an alternative for a part of the fine aggregate were tested as a basic study for the usage of waste wood as a lightweight aggregate for concrete. For the test, the waste wood of the pine tree was crushed, sifted through No. 8(2.4 mm) sieve, and then dried for 24 hours at
