Design of Bags from Recycled Plastic Waste

Abstract

This study aims to analyze the properties and types of plastic waste, design products from plastic waste, and assess the satisfaction of these designs. Data collection and analysis focused on calculating the average and standard deviation of the satisfaction scores.
The research findings indicate that designing products from plastic waste to meet consumer needs involves creating modern and simple designs. The researcher selected high-density polyethylene (HDPE) No. 2 and polypropylene (PP) No. 5 for this purpose. The plastic pieces were designed in the shapes of the letters "M" and "i," which are part of the brand name "Mia Compassion." These pieces were then strung together to create a unique pattern specific to the brand.
The researcher chose to use a heat press method to handle the materials, resulting in plastic sheets of the desired thickness and color. These sheets were then cut into specific shapes and assembled into four styles of bags. Round stainless steel loops and metal straps were used as supplementary materials to enhance durability and elevate the plastic waste into valuable, aesthetically pleasing products. The logo was designed as a simple and modern logotype, conveying environmental friendliness.
To process the materials, a heat press method was used to create plastic sheets of the desired thickness and color. These sheets were then carved into pieces according to the design and assembled into four styles of bags, catering to female students, tourists, and working professionals. The bags were reinforced with round stainless steel loops and metal straps for durability, adding value and aesthetic appeal to the plastic waste products. The logo was designed to be simple and modern, with rounded curves to convey environmental friendliness.
The assessment of product design satisfaction revealed very high satisfaction levels. The creativity of the designs received an average score of 4.60 (S.D. = 0.60), satisfaction with the plastic pattern scored an average of 4.54 (S.D. = 0.60), and logo design satisfaction scored an average of 4.68 (S.D. = 0.47), all within the "very good" criteria.
