Miami-Dade is getting creative about one of its stinkiest problems: garbage.
鈥淭he secret is our waste is somebody else鈥檚 treasure,鈥 Mayor Daniella Levine Cava said Saturday at the old South Dade landfill in Homestead.
The county teamed up with the Miami-Dade Innovation Authority, a non-profit that connects businesses to government, to pick three start-ups for pilot projects aimed at reducing and recycling more of our trash. Each company gets $100,000 to kick off its idea.
Two of the winners are homegrown: Clean Earth Innovations, which turns yard waste into 鈥渂iochar,鈥 and Fertile Earth Worm Farm, which transforms food scraps and other organic waste into compost. The third winner is Scrapp, an app that helps people figure out what goes where when tossing out their trash. More than 80 companies applied from across the U.S. and abroad.
鈥淲e believe this marks a new era in waste management in Miami-Dade County,鈥 Lanette Sobel, founder of Fertile Earth Worm Farm, said.
The challenge was sparked by the aging Covanta incinerator in Doral burning down in 2023, forcing the county to ship garbage some 100 miles north, Levine Cava said. But that challenge, she said, created opportunity.
By partnering directly with small businesses, the county hopes to cut through some of the 鈥渞ed tape鈥 that usually slows big government changes, she said.
Having organic materials in the landfill is a problem because when it breaks down it creates methane, a 鈥済reenhouse gas鈥 much more potent than CO2. About 30 percent of the county鈥檚 trash is food and other organic waste, and another 10 percent is yard waste. The new projects aim to bring those numbers down and stretch the life of a landfill that鈥檚 nearing capacity.
That includes hundreds of thousands of tons of green waste every year. Clean Earth Innovations CEO Harold Gubnitsky said the company plans to open a biochar facility at the South Dade landfill by January. Biochar is made by 鈥渂aking鈥 waste 鈥 a process called pyrolysis that heats materials without oxygen.
The result looks like charcoal and can boost soil health. Research suggests it may even filter water or be added to animal feed.
鈥淚t鈥檚 fighting climate change, turning waste into value and creating a circular economy, because now there鈥檚 an opportunity to create jobs around these processes,鈥 Gubnitsky said.
Another big issue: people don鈥檛 recycle properly. About 40 percent of recyclable materials end up contaminated. That鈥檚 where Scrapp comes in.
鈥淚f we make information radically accessible to where nobody has a question about what goes where, and you democratize that access to where businesses and communities can all be on the same wavelength, that鈥檚 going to drive the real change,鈥 said Mikey Pasciuto, co-founder and chief sustainability officer at Scrapp.
