300,000 tons of waste tires are annually being produced with development of the automotive industry in Korea. Landfill and incineration treatment system are causing the economic problem through secondary environmental pollution and waste. Therefore, as one of the ways to take advantage of this, Thermo-Plastic Vulcanized (TPV) composite was prepared by the ground waste tire and plastic powders. The waste tire powder was gained by mechanical fracturing through crushers. The waste tire powder was ground by a shear crushing method and a 2-stage disk mill method instead of cutting crushing one. The waste tire powder of 50 mesh was mixed with Polypropylene(PP) in various proportions. TPVs were prepared by an extrusion, and tensile and impact tests were performed. In addition, the same experiments were repeated in 40, 80, 140 mesh conditions in order to observe size effect of waste tire powders.

2008년부터 유럽연합국가, 일본, 러시아 등은 2012년 연간온실가스 배출량을 평균적으로 1990년의 배출량보다 약5%정도 낮은 수준으로 제한하여야 한다. 이러한 온실가스 배출량 감축을 위해서 선진국들은 국내적으로는 에너지효율향상, 신재생에너지 보급확대 등의 정책을 시행하고 있으며, 이를 보다 낮은 비용으로 감축하기 위하여 국내 또는 역내 온실 가스배출권 거래제도를 도입하여 시행하고 있다. 이들 국가들은 국내정책만으로는 최소의 비용으로 온실가스 감축목표를 달성할 수 없다는 인식하에 동유럽국가, 그리고 중국 등 개발도상국들에 대한 온실가스 감축사업에 투자를 하여 온실가스 감축의 일부 또는 전부를 자국의 감축실적으로 인정받는 공동이행체제(joint implementation), 청정개발체제(clean development mechanism)사업을 전개하고 있다.

In this study, waste polypropylene and waste ground rubber tire(WGRT) composites were prepared by using a modular intermeshing co-rotating twin screw extruder. The effect of three main factors such as WGRT contents, particle size, compatibilizers on the properties of waste PP/WGRT composites was extensively investigated. Tensile strength of the composites was decreased with an increase in WGRT contents, whereas elongation at break and impact strength were increased. The tensile strength, elongation at break and impact strength of the composites with the smaller size of the WGRT were more enhanced. Addition of PP-g-MA into waste PP/WGRT composites exhibited better tensile strength. However, elongation at break and impact strength were slightly decreased with increasing of PP-g-MA. On the other hand, tensile strength, impact strength and elongation at break of the composites were increased by adding the EPDM-g-MA and SEBS-g-MA. Especially, elongation at break was significantly increased compared to the composite with PP-g-MA.

폐기물의 양이 급격히 증가하고 있는 현재, 국내는 물론이고 전 세계적으로 자원의 고갈에 대한 심각성을 인식하고 폐기물을 재활용하여 가능자원으로 만들기 위한 방법을 모색하고 연구하는 등 미래자원을 확보하기 위한 노력을 꾸준히 하고 있다. 하지만, 폐철, 폐지, 폐플라스틱, 폐유, 폐타이어 등의 폐기물에 대해서는 많은 관심을 가지고 재활용 기술을 연구하는 등 그 중요성에 대해 인식하고 있는 반면, 유리제품의 재활용에 대해서는 그 중요성이 인식되지 못했다. 그래서 월간 ‘재활용’지에서는 폐유리병 재활용 현황, 기술 등에 관한 특집기사와 더불어 유리제품 재활용에 대한 인식을 고취시키기 위해 현장의 목소리를 듣고자 유리재생원료(cullet)를 생산하는 쎄로라인을 찾아 업체탐장 코너에 소개한다.

The pyrolytic behavior of waste tire under microwave heating was investigated. Experiments were conducted using a lab- and bench-scale system to delineate the effects of microwave output power on the response. As the results of experiments, it was found that as the microwave output power was increased between 0.84 and 3.04 kW/kg, the oil yield and required time rapidly increased and decreased, respectively. With further increase of the microwave output power, the oil yield and required time did not change significantly.

The 10t/d pyrolysis demonstration plant have been developed for waste tire recycling treatment and value added commercialization. The initial plant model had been started under 2.4t/d capacity with continuous operation, and the commercial plant has been achieved to the 120t/d based on demonstration plant having the tube reactor with chain conveyer attached disk. The next generation pyrolysis plant for waste tire is reviewed and the assignment for plant development is presented briefly.

The 120t/d pyrolysis commercial plant for waste tire recycling have been constructed in Malaysia and is going to be operated. The plant have the tube reactor with chain conveyer attached disk developed in demonstration research stage. The reactor temperature for commercial plant is about 500deg.C and reactor inside pressure is -100$\sim$-120mmHg. Non-condensable gas is used as fuel for pyrolysis heat source, and the exhausted heat is recovered for cogeneration to produce steam and electric power of 600kw.

The effects of monaural beating sound generated according to the number of tire pitch blocks to human body are measured from experiments, and the possibilities of similar positive effects of enhancing alpha waves in human brain are investigated. Due to the requirement of repeatability and measurement conditions, recorded sounds of the tire noise are used for the experiment in a quiet room and human responses are measured using HRV. Although the number of statistically meaningful results was small, it showed that positive human reactions are probably possible.
