  • 태양에너지 이용이 크게 역설된지도 벌써 상당한 년월이 흘렀으나 대규모 이용은 아직 실용화되지 못하고 있다. 다수의 반사경을 사용하여 태양 광선을 탑 위에 올려놓은 보일러에 집중시켜 여기에서 발생하는 수증기를 이용하여 터어빈을 회전, 발전하는 태양열발전 방식의 10MW의 파이롯드 플랜트가 금년중에 미국에 건설될 예정으로 있다. 이것은 앞으로 100MW의 발전소를 현실시키기 위한 것으로 기술적으로는 큰 어려움이 없고 대량생산이 되면 경제적으로도 원자력발전보다 오히려 유리하다고 한다. 기상조건과 지리적조건이 다른우리나라에서는 실현이 어렵겠지만 이러한 류의 구상은 우리나라에서도 가능할 것이다. 이 헬리오스타트(시계장치로 회전하는 반사경에 의하여 태양의 반사광선을 일정한 방향으로 보내는 장치)를 사용하는 발전에 대하여 휴우스톤대학의 물리학 교수이며 태양 에너지 연구소장인 힐데프란드박사와 같은 물리학교수이며 동연구소의 부소장인 밴드할박사가 상세한 논문을 발표하고 있다. 다음에 그 논문의 요약을 소개한다.

  • Plastic supply and recycling are increasingly becoming matters of social concern. In our country, Extended Producer Responsibility(EPR) system has been adopted in 2003 to expand recycle and reuse of waste resources at producer side, and due to expansion of the EPR system, amount of the mixed plastic waste generation has been drastically increased. Plastic-plastic separation is most fundamental technique to achieve effective plastic recycling. This paper reviews recent developments in plastic-plastic separation techniques and describe future tasks. The mechanisms of each separation which contain gravity separation, electrostatic separation, flotation, and separation of automotive shredder residue are described, and commercial scale and lab-scale results are introduced.

  • For treating a huge amount of plastic waste with the environment problem, pyrolysis of plastic waste into alternative fuel oil is one or important issue in recycling methods. This study was introduced over the trend or generation of plastic waste, in Korea pyrolysis technology in domestic and foreign countries, basic technology in pyrolysis process and new technology of pyrolysis developed in KIER (Korea Institute of Energy research). The characteristics of process developed in KIER are the continuous loading treatment or mixed plastic waste with an automatic control system, the minimization of wax production by circulation pyrolysis system in non-catalytic reactor, the reuse of gas produced and the oil recovery from sludge generated in pyrolysis plant, which have greatly the advantage economically and environmetally. The experiment result data in 300 ton/yr pilot plant showed about $81\;wt\%$ liquid yield for 3 days continuous reaction time, and also the boiling point distribution of light oil (LO) and heavy oil (HO) produced in distillation tower was a little higher than that of commercial gasoline and diesel, respectively.
