NuLeaf Tech, Inc. is a manufacturing company based in Cupertino, California, specializing in wastewater treatment systems and solar cells tailored for breweries, wineries, and other agricultural producers. Founded in 2015, the company addresses the pressing issue of inadequate on-grid wastewater treatment plants, particularly impacting low-income communities. NuLeaf Tech offers an innovative solution with its NuTree, an on-site wastewater treatment device that allows users to manage their water treatment needs effectively and affordably. This modular system, which can be easily maintained like a small garden, is designed to scale from individual households to larger businesses, with costs under $10,000 per unit. The NuTree operates on a circular, zero-waste model incorporating water recycling, bioenergy, and crop cultivation. NuLeaf Tech has begun generating revenue from various clients, including Mastercard and local breweries, and is exploring pilot projects in regions such as Madagascar, India, and Portland, Oregon. The company aims to expand its reach, particularly in the Pacific Northwest, focusing on tiny homes and rural communities.
