In 2023, UKL created a Sustainable Materials Department, focusing on the advancement of Taiwan's local environmentally sustainable recycled materials, notably pineapple
leaves
fiber (PALF). PALF, derived from indigenous pineapple leaves, fills a void in Taiwan's textile industry by utilizing locally sourced agricultural waste. With a dedicated emphasis on the development of Taiwan's indigenous natural fibers, PALF pioneers a new era of eco-conscious textile solutions. Utilizing recyclable, zero-carbon emission pineapple leaves, UKL establishes Taiwan's premier sustainable yarn and fabric trial production line, dedicating efforts to the creation of environmentally friendly textile products. By championing waste recycling and reuse, UKL aims to catalyze a shift towards a more eco-friendly, sustainable textile and fashion industry in Taiwan.
