In the present work, a new separation system with rotating rakes has been developed to separate the film-based plastics from the recyclable materials, and environment assessment is also carried out during operation of the device. Capacity of the device was about 5.3 ton/hr at a rakes rotation speed of 26.0 rpm (the number of rakes in the 1st, 2nd and 3rd trials were 39, 52 and 48, respectively) and a belt conveyor speed of 38.5m/min, which satisfied the initial design capacity (5.0 ton/hr). Recovery ratio and purity of the plastic films were 92.6% and 96.5%, respectively at a rotation speed of 28 rpm. The levels of noise, vibration and particulate emission were below material standard regulatory limits. Plastic refused fuel (RPF) was also prepared with the recovered films. The calorific value and chlorine content of the prepared RPF were 9,740 kcal/kg and 0.18%, respectively which satisfy the first grade quality specification of the Korean RPF standard. As a result of this work, recovery of energy resources from the municipal solid waste is possible by adopting the developed separation device.

Three leaf vegetables, namely green lettuce, red lettuce (Lactuca sativa) and red-veined chicory (Cichorium intybus) were grown in minigreenhouses covered with two new functional films and conventional polyethylene film (PE). Seedlings of leaf vegetables were transplanted in a plastic troughs filled with soil-perlite mixture. Two functional films were made from polyolefin (PO) material. Measurement of optical characteristics showed that polyolefin films have better transmittance for the photosynthetic active radiation (PAR, 400-700nm) and higher absorptance for the ultraviolet radiation (UV, 300-400nm) in comparison with the conventional PE film. After three months of utilization higher loss in PAR transmittance was observed for conventional PE film. Leaf vegetables growth was enhanced and yield was increased in greenhouses covered by new functional films.

PVA필름은 휴대폰, 카메라폰, 컴퓨터모니터, LCD TV등 편광필름이 사용되는 TFT-LCD 제품에는 반드시 필요한 핵심부품으로, 최근 인조대리석 제조용 필름, 분리필름, 내(耐)산소투과성 포장필름 등에도 활용범위를 넓혀가고 있는 신소재이다. 그러나 PVA필름은 일본이 PVA특성조절기술을 갖고 있어 그동안 일본에서 전량 수입해 사용해 온 것이 현실. 지난 1990년 설립된 이래, 국내 최초로 순수국내 기술로 고온수용성 부직포를 개발하며, 생산해 온 (주)텍스테크(대표이사 신재균)가 폐 부직포를 재활용해 LCD용 폴리비닐알코올(PVA) 필름을 제조하는 기술을 개발, 업계의 주목을 끌고 있다. 신재균 사장을 만나 폐부직포를 이용한 PVA 필름제조 기술개발 경위와 기대효과를 들어보았다.

The NR films were prepared with mixing of natural rubber latex(NRL) with various additives, and NR/CR films were prepared by blend ratio of chloroprene rubber latex(CRL). The swelling degree and the mechanical properties of these films were measured according to the procure time. As a result, optimum condition were showed the swelling degree : 80~85%, precure time : 48~60hrs., and tensile strength was reduced but elongation was increased as increasing the blend ratio of CRL. On the mechanical properties of films prepared by different dipping process in these optimum condition, the tensile strength and tear strength of NR/CR films by one dipping process are better than NR-d-CR films by two dipping process. The surface of these films were observed with scanning electron microscopy(SEM). It was found that phase separation was occured as increasing the blend ratio of CRL.

창란젓갈은 최근 염도 8％ 이하의 양념젓갈 형태가 보편화되어, 일정 중량의 규격포장으로 유통되는 사례가 많은데 대표적인 포장 형태는 병과 필름포장을 들 수 있다. 그러나 창란젓갈을 비롯한 젓갈류 대부분의 포장은 병포장보다 상대적으로 단가가 낮은 필름포장 재질인PE(low density polyethylene)를 사용하고 있는데, 이 경우 숙성이 끝난 정상적인 젓갈 제품을 충진하더라도 PE 필름의 가스투과도가 높아 젓갈 냄새가 누출되어 나옴으로서 소비자에게 불쾌감을 주는 경우가 많다. (중략)
