It relates to an eco-friendly biodegradable vinyl produced.
일반적으로, 폴리에틸렌을 이용하여 제조된 비닐 봉투는 얇고 투명한 필름 형태로서, 폴리에틸렌 합성수지를 주원료로 하여 만들어진다. 이러한 비닐 봉투는 공업용(예를 들면, 포장, 방수 등), 농업용(예를 들면, 작물의 보온 및 생육 촉진 등), 일상 생활용(예를 들면, 각종 봉투) 등으로 널리 사용되고 있어, 우리 생활 주변에서 매우 빈번하게 사용되는 생활 필수품으로 자리 잡고 있다.In general, a plastic bag manufactured using polyethylene is in the form of a thin transparent film, and is made of polyethylene synthetic resin as a main raw material. Such plastic bags are widely used for industrial purposes (e.g., packaging, waterproofing, etc.), agriculture (e.g., for keeping warm and growing crops), and everyday life (e.g., various bags). It is becoming a living necessity that is very frequently used in.
특히, 근래에는 온라인 구매가 폭발적으로 증가하고 있고 온라인으로 구매된 제품은 제품에 따라 다르겠지만 포장용 봉투 등에 의해 포장되어 배송되기 때문에 포장용 또는 택배용 비닐 봉투의 수요도 급증하고 있는 실정이다.In particular, in recent years, online purchases are explosively increasing, and since the products purchased online vary depending on the product, the demand for plastic bags for packaging or parcel delivery is rapidly increasing because they are packaged and shipped in packaging bags.
하지만, 이러한 비닐은 사용후 처리를 위해 소각 시에는 다이옥신과 같은 유해물질을 발생시키고, 많은 이산화탄소 발생으로 대기 중 온실가스 효과를 가속화시키는 문제가 있다. 또한 이러한 비닐은 화학적 및 생물학적으로 안정하기 때문에 거의 분해되지 않으므로, 매립지의 수명을 단축시켜 지구 토양 오염의 원인으로 문제를 야기하고 있다.However, such vinyl generates harmful substances such as dioxins when incinerated for post-treatment, and there is a problem of accelerating the greenhouse gas effect in the atmosphere by generating a lot of carbon dioxide. In addition, since vinyl is chemically and biologically stable and hardly decomposed, it shortens the life of landfills, causing problems with global soil pollution.
최근 들어서는, 녹색성장 투자재원 마련 및 지구의 온실가스 감축을 위해 탄소세와 탄소배출권 거래제도에 대한 검토 및 논의가 활발히 이루어지고 있는 실정이어서 이를 해결하기 위한 방안으로 전분을 함유하여 미생물로 비닐을 분해하여 썩게 하는 생분해성 비닐이 개발되고 있다. In recent years, carbon tax and carbon emission trading systems have been actively reviewed and discussed in order to secure green growth investment resources and reduce global greenhouse gas emissions. To solve this problem, vinyl is broken down into microorganisms containing starch and Biodegradable vinyl is being developed.
상기 전분은 생분해성 비닐(또는 필름)을 제조하기 위한 천연물질로서 그 분해성능이 우수하여 널리 사용되고 있지만, 일련의 제조공정을 거쳐 생산되는 원료로서 이를 대신하여 임의의 제조공정을 따르지 않고 자연적으로 발생되는 폐자원을 변성처리를 하지 않고 그대로 활용하는 방안에 대한 연구가 필요하다. 또한, 전분 등을 이용하여 제조된 종래의 일반적인 생분해성 고분자 물질은 강도 및 내충격성이 떨어져 물성 측면에서 미약한 문제점이 있으며, 식량자원을 소모시키고, 소각 시 매연이 발생되며, 제품의 단가가 비싸지는 등의 단점이 있다.The starch is a natural material for producing biodegradable vinyl (or film) and is widely used because of its excellent degradability. However, it is a raw material produced through a series of manufacturing processes and instead occurs naturally without following any manufacturing process. It is necessary to study how to utilize the used waste resources without denatured treatment. In addition, the conventional biodegradable polymer material prepared using starch, etc., has a weak problem in terms of physical properties due to its strength and impact resistance, consumes food resources, generates soot when incinerated, and increases the cost of the product. There are disadvantages.
따라서, 전분을 사용하지 않고서, 제조할 때 주로 LDPE(저밀도폴리에틸렌) 또는 HDPE(고밀도폴리에틸렌) 70 중량%에 바이오닐 30 중량%를 첨가하여 사용함으로써 시간 경과에 따라 비닐을 잘게 부서지게 하는 생붕괴성 비닐(또는 필름)이나, 또는 비닐 봉투 또는 필름을 제작할 때 별도의 첨가없이 마스터배치(M/B) 원료 그대로 사용함으로써 시간 경과에 따라 미생물이 비닐을 분해하게 하여 썩게 하는 생분해성 비닐(또는 필름)에 대한 개발이 절실한 실정이다.Therefore, biodegradability that breaks down the vinyl over time by using 30% by weight of bionil in addition to 70% by weight of LDPE (low density polyethylene) or HDPE (high density polyethylene) without using starch Biodegradable vinyl (or film) that causes microorganisms to decompose vinyl over time by using it as a masterbatch (M / B) raw material without additional additions when producing vinyl (or film) or plastic bags or films. The development of is urgently needed.
또한, 녹색제품 구매촉진에 관한 법률」제2조의2에서 녹색제품의 범위에 종량제쓰레기봉투(폐합성수지 40% 이상 사용)를 포함하고 있으며, 동법 제6조에 따라 공공기관에서 녹색제품 구매 의무화가 추진되고 있는 실정이다.In addition, Article 2-2 of the Act on the Promotion of Green Products Purchasing Act includes green garbage bags (using more than 40% of synthetic resin) in the range of green products, and mandatory purchase of green products by public institutions pursuant to Article 6 of the Act. It's happening.
따라서, 폐합성수지를 40% 이상 사용하는 비닐(또는 필름)의 개발에 대한 요구가 점증하고 있다.Therefore, there is an increasing demand for the development of vinyl (or film) using 40% or more of waste synthetic resin.
