Composite Materials of Urban Development for Low-Run Sustainable Design

This study investigates the development of composite materials from biodegradable and industrial waste, with an emphasis on the reuse of coffee grounds, wood chips, and fruit peels, bonded with a plant-based resin. The objective is to create sustainable alternatives for design, reducing the use of nonrenewable resources and promoting the reuse of agro-industrial waste. The adopted methodology was divided into three main stages: (i) selection of materials and product definition, considering their physicochemical properties and functional requirements; (ii) fabrication of composite panels, including material preparation, mixing, and pressing; and (iii) machining and cutting to achieve the final prototype shapes. The developed composites demonstrated competitive mechanical performance compared to those reinforced with synthetic fibers, along with significant environmental benefits. As a key outcome, prototypes such as the "Alce Porta Copos", "Estante Panetone", and "Prateleira Café Caramelo" were created, highlighting the feasibility of their application in sustainable design products.
