In a novel approach to sustainable construction, a team of researchers led by Siswanti Zuraida, Bart Dewancker from Kitakyushu University in Japan, and Romi Bramantyo Margono, have pioneered a method to utilize non-degradable waste, notably disposable diapers, as composite materials for building low-cost housing. This compelling study is attracting substantial interest within the architectural community, providing an enticing alternative to traditional building materials, which can account for up to 80% of a dwelling's overall worth.

The research centered on the potential of disposable diaper waste in the construction of affordable housing, adhering to Indonesian building standards. The results showcased that disposable diaper waste could make up to 10% of structural components and 40% of nonstructural and architectural components in a housing unit. A prototype housing structure demonstrated that approximately 1.73 m^3 of disposable diaper waste could be repurposed for a housing area of 36 m^2.

Sustainable construction has been a major focus for architects, as the high cost of land and building materials poses a significant hurdle to affordable housing. In developing countries, these costs often prevent occupants from meeting other essential living costs, hampering the fulfillment of fundamental human rights. This research offers a potential solution to this problem, suggesting a pathway to making housing more attainable for the urban poor.

Traditional building regulations and standards often hinder the use of more locally appropriate and readily available building materials, as well as the implementation of cost-effective and environmentally friendly construction technologies. The incorporation of non-degradable waste as a building material could help address these issues, providing a sustainable, cost-effective alternative to traditional building materials. This could have a profound impact on the affordability of housing, particularly in developing countries.

The researchers argue for the need for policies that encourage access to building materials that are both appropriate and economical. They also call for robust research and development efforts into cutting-edge building techniques, which include environmentally friendly construction plans and methods and energy-efficient, low-pollution technologies.

The concept of using non-degradable waste, such as disposable diapers, in construction is not new. However, this study represents a significant stride forward by providing tangible evidence of the viability of this approach. Despite the promise shown by these results, the researchers emphasize the need to consider the durability of these recycled materials. They must be durable enough to withstand various environmental factors and have a lifespan that is comparable to conventional materials.

This research signals a potential paradigm shift in sustainable construction, offering the possibility of transforming waste materials into valuable resources for building. While further research is needed to fully comprehend the long-term implications of this approach, this study shows promise in our journey toward more sustainable and affordable construction methods.
