대만의 소과류 작물의 생산량은 적지만 생산 시스템은 매우 발달이 되어있다. 2017년 기준 대만 내 소과류 전체 재배면적은 2826.6 ha로 이 중 포도(500.33 ha)와, 딸기(67.56 ha)가 가장 많이 재배되고 있다. 다음으로는 오디나무 (Morus alba L.), 베이베리 (Myrica rubra Sieb. et Zucc.), 인도 구스베리(Phyllanthus emblica L.) 순으로 재배가 많이 되고 있다. 현재 대만은 새로운 품종 육성과 재배 시스템 개발을 위해 많은 노력을 기울이고 있는데 최근 블루베리를 대상으로 대만 기후에 적합한 저온요구도가 낮은 품종을 육종 중에 있으며 또한 포도와 딸기는 연중 생산이 가능한 재배법이 개발이 되어 농가에 보급되었다. 대만은 40년 이상 생과 위주의 포도 품종으로 생산을 하였으나, 최근에는 와인용 포도 품종 등을 육종 연구가 지속적으로 이루어지고 있다.

Reuse, recycling and recovery (3R) of industrial wastes are common and encouraging in Korea. Industrial symbiosis is one of typical methods for implementing 3R and has been defined as engaging “traditionally separate industries in a collective approach to competitive advantage involving physical exchange of materials, energy, water, and by-products”. The keys to industrial symbiosis are collaboration and the synergistic possibilities offered by geographic proximity. Recently, several countries in East Asia such as Taiwan, South Korea, Japan and China are promoting ‘designed’ symbiosis networks in various industrial complexes based on their national Eco-industrial Park (EIP) demonstration programs. Despite the recently promoted EIP initiatives worldwide, only very few studies furnish the operational and functional details of ‘designed’ industrial symbiosis networks, starting from the planning to implementation stage. The production of terephthalic acid (TPA) in Korea is 6.5 million ton based on 2011. The production of waste generated in the process of TPA is about 15,000 ton/yr and included useful materials like residue TPA as well as isophthalic acid (iPA), benzoic acid (BA) and p-toluic acid (p-TL). Until now, TPA waste was incinerated due to high caloric value. This study was conducted for recovery of valuable materials from industrial waste and utilization of recovered material as an example of Korean EIP. In this study, the experiment was performed to separate above four materials from the waste by solvent (methanol and water) extraction. The solubility of TPA (0.1g/100g) for methanol is relatively low compared to other materials. Also the solubility of BA (68g/L at 95℃) and p-TL (11.6g/L at 98℃) for water is relatively high in comparison with other materials. Finally, BA was separated from p-TL by molecular distillation system. The purity of recovered materials was analyzed by ultra-high performance liquid chromatography (Waters Xevo TQ system). The recovery rate and purity of BA is 90% and 93%. The recovered BA could be recycled the companies which are produced plastic plasticizer and paints.
