Abstract

The daily use of plastic bags on a large scale has an impact on the increasing amount of plastic bag waste generated. Responding to these problems, the author initiated the utilization of plastic bag waste in the interior field, namely by upcycling plastic bag waste using crochet techniques for making upholstery on pouf products. That way in this design can be formulated a problem of how to process plastic bag waste with crochet techniques into upholstery on pouf products. The purpose of designing this work is to provide alternatives and variations in the processing of plastic bag waste using crochet techniques. This design uses the method of creation proposed by Palgunadi (2007), which includes three processes of planning and making products, namely the exploration process, extraction process, and termination point. The results obtained from this design are that plastic bag waste, especially HDPE types, can be made into plastic fibers because this plastic waste has a medium thickness, but is still strong and very much available. Furthermore, to process plastic waste into plastic fibers, steps are needed such as sorting, cleaning and then cutting plastic bag waste to produce plastic fibers that are ready to be crocheted to produce upholstery poufs that are in accordance with taste.

Abstract

The textile industry plays a vital role in human life but also ranks among the highest contributors to global environmental pollution. Textile waste is often non-biodegradable, leading to severe environmental issues such as water contamination and increased greenhouse gas emissions. One promising solution lies in eco-friendly recycling methods using biomaterials. This study explores the use of sodium alginate, a brown algae-derived biopolymer, as a fiber-binding medium in the recycling of textile waste through a crosslinking method with calcium chloride (CaClâ‚‚). Sodium alginate, which dissolves easily in water, reacts with calcium ions to form a strong and elastic gel. In this process, textile waste in the form of fabric and yarn is broken down into staple fibers and then recombined using sodium alginate and calcium chloride. The crosslinking mechanism strengthens fiber bonds and produces a new alginate-based yarn material suitable for sustainable textile development. Results indicate that this combination forms a water-resistant, flexible, and environmentally friendly binder. Therefore, this method offers an innovative alternative for managing textile waste while promoting circular economy principles in the fashion industry.
