Eco-design product of alternative dishwashing detergent

Current industries continue to pursue products that reduce impacts on the environment and human health called eco-friendly products. Eco-design is used as a tool in the manufacturing and service sectors to improve the sustainability of products by combining environmental facet into the design process where the product impacts are defined. This study explored the dishwashing liquid which is widely used in Thailand considered as a household product. Dishwashing liquid generated monthly waste from bottle packaging. Thus, those bottles are the one causes of plastic waste in the world that cannot be disregarded as other single-use products. Additionally, conventional dishwashing liquid released into the environment is harmful to nature, animals, and human health. The research aims to understand customer insights, needs, and opportunities to improve the dishwashing liquid that less impact on the environment based on eco-design strategies.Online questionnaires and focus group interviews are the methodologies for gathering data undertaken in Thailand. Furthermore, this study summarizes the main current approached and practical tools including life cycle assessment (LCA), MET matrix, and lifecycle design strategies (LiDS) wheel for implementing eco-design strategies. Ingredients of detergent and packaging materials are the main factors affecting the environment such as natural land transformation, natural resource depletion, landfill, air pollution, toxic ash, groundwater pollutions, and waste. The finding results emphasize a high customer value with less environmental impact along a product life cycle. When focusing attention on designing eco-friendly dishwashing detergent. The designer should give important continue developing the product formulations, non-water ingredients, and improving/ eliminated packaging to reduce the environmental impact of conventional dishwashing liquid. Alternative dishwashing mostly takes place in new concept development, selection of low-impact materials, and reduction of materials in eco-design strategies wheel. Most users face problems of skin drying and irritation. Besides, texture, foaming, and scent are essential to decide the alternative ingredients to satisfy user needs. All contents of design knowledge here will be useful for designers and product developers. As small problems together can create a great global impact, especially the daily product that everyone used, designers can create innovation by address the environmental problem of an existing product by ecodesign strategies.
