UN-Habitat calls for innovative solutions and best practices that transform waste to wealth. Applicants may submit technologies, solutions, ideas, or approaches that change the way we think about, use and treat waste (solid, liquid, domestic, industrial and commercial). The best 20 submissions will be published and showcased as part of World Habitat Day. Applications are open to everyone who is passionate about solving the challenges of waste management. Submissions have to be received by 06 September 2019. Details
