Although bioplastics have begun to achieve some degree of commercial success, the industry is still in an embryonic stage. For biodegradable plastics, the market will continue to evolve as products become more widely avail- able and performance is improved to more closely approximate that of conventional polymers such as PE, PP, PET and PS. Development of brand-new biodegradable plastics is unlikely in the near term, as the most promising candidates for commercial viability - including starch-based resins, polylactic acid (PLA), polyhydroxyalkanoates (PHAs) and cel- lulose-based resins - have already been identified. Rather, future innovation will come from efficiency improvements in the production process and the development of compounds and copolymers which optimize the performance of these resins. Non-biodegradable plant-based plastics, such as bio-based versions of PE and PVC, have yet to enter the commercial market, although significant capacity is planned for the near future. For this segment of the bioplastics industry, market success will depend mostly on lowering production costs so that prices are in line with the petroleum- based resins they compete with. Additionally, marketing efforts on the part of resin producers and product fabricators will also be a key factor, as effectively promoting the bio-based nature of these resins will lead customers to give bio- plastic products preference over similarly priced traditional plastics. Key words: bioplastics, biodegradable, non-biodegradable, starch-based resins, PLA, PHAs 서 론 이오플라스틱이란 바이오매스(biomass) 를 원료로 사용하 여 제조된 고분자 플라스틱을 말하며, 상용화된 가장 대 표적인 제품으로 PLA (polylactic acid) 등을 들 수 있다. 기존 의 바이오폴리머는 생분해성에 초점이 맞추어져 있어 생분해성 고분자 전체를 바이오폴리머라고 하였고, 바이오플라스틱은 바 이오매스 기반의 고분자 플라스틱 전체를 의미하므로 여기에는 생분해성이 아닌 고분자들이 포함되어 있다. 바이오플라스틱이 란 개념은 지구온난화와 밀접한 관계가 있다. 지구온난화의 주 요인이 이산화탄소로 인식되면서 석유기반 고분자플라스틱을 대 체할 수 있는 새로운 친환경 소재가 필요하게 되었고, 아래의 Figure 1 과 같이 이산화탄소 Neutralization 개념이 등장하면서 바이오매스 기반 고분자가 바이오플라스틱이란 이름으로 사용 되게 되었다. 이산화탄소 Neutralization 개념을 간단히 설명하 면, 바이오플라스틱은 바이오매스를 원료로 제조되고, 폐기되어 분해될 때 이산화탄소가 발생되지만 다시 원료인 식물의 성장 에 사용되므로 전체적으로는 이산화탄소가 발생되지 않는다는 개념이다. 1) * 책임연락저자: [email protected]바 Figure 1. 바이오플라스틱의 CO 2 Neutralization 개념도.
