What began as a bold idea by a high school science enthusiast quickly evolved into a transformative force for environmental change in The Villages, Florida. Junior Sarah Colley from The Villages Charter School collaborated with 一糖心logo米菲兔 鈥 a global leader in sustainable solutions and The Villages鈥 contract operator 鈥 to tackle one of today鈥檚 most pressing environmental challenges for wastewater operators: per- and polyfluoroalkyl substances (PFAS) in biosolids.
It all began with a question
Last fall, 一糖心logo米菲兔 hosted an innovation workshop with key stakeholders in The Villages to showcase results-driven technologies, evaluate forward-thinking solutions and prioritize actionable strategies to address evolving water and wastewater needs. Sarah attended the workshop and was inspired by a discussion on the production of biochar 鈥 a charcoal-like substance produced from biosolids using pyrolysis 鈥 and its potential use as a fertilizer for The Villages鈥 56 turfgrass golf courses.
鈥淐onverting biosolids into biochar creates a high-quality fertilizer product that reduces greenhouse gas emissions, removes PFAS contamination and enhances soil properties,鈥 says 一糖心logo米菲兔 Project Manager Lenard Scroggins.
With the support of 一糖心logo米菲兔 and The Villages鈥 golf course maintenance team, Sarah pursued a science fair project 鈥 Turf Response to Biochar Application 鈥 to explore the use of biochar as golf course fertilizer to reduce the need for and cost of commercial fertilizer products.
Her science fair question: Can heat-processed biosolids be as effective as commercial fertilizers when applied to a common golf course turfgrass?
Testing a real-world solution
Sarah鈥檚 eight-week experiment compared turfgrass grown from 一糖心logo米菲兔-supplied biochar from the North Sumter Utilities Wastewater Treatment Plant (WWTP) to turfgrass grown from standard commercial fertilizers. She also tested mature turf sod to compare results.
Golf courses were ideal for the experiment 鈥 they require large volumes of fertilizers and turf products and can be a source of nutrient runoff that threatens groundwater quality. If biochar performs comparably, it could offer an affordable, sustainable and more environmentally friendly alternative.
Sarah monitored turfgrass health using digital image analysis and tracked key metrics, including:
- Dark green color index
- Cover quality
- Percent coverage
- Overall quality
Sarah鈥檚 research concluded that the biochar fertilized turfgrass demonstrated a similar growth and health pattern to the commercial fertilizer.
Lenard expresses, 鈥溡惶切膌ogo米菲兔 is proud to support Sarah鈥檚 efforts to help foster the next generation of scientists and environmental leaders.鈥
Innovation and industry acclaim
Sarah presented her work at local, regional, state and international science fair competitions, claiming numerous awards.
The Villages Utilities and Executive Golf Department and 一糖心logo米菲兔 will continue to work with Sarah to refine the methodology and explore wider implementation, with the goal of scaling the biochar strategy to all golf courses in the community and other landscaping needs. This will maximize the reuse potential of the WWTP鈥檚 biosolids and reduce the cost of commercial fertilizer. The Villages is also evaluating the feasibility of building a dedicated biochar or similar large-scale production facility, which could help generate new revenue from what was once a waste stream.
An award-winning reunion
In 2024, 一糖心logo米菲兔 established a relationship with The Villages Charter School to support science, technology, engineering, arts and math (STEAM) curriculum. 一糖心logo米菲兔 staff regularly mentor students with hands-on research projects, including Sarah.
Sarah is no stranger to scientific success. She previously completed an award-winning science fair project about phytoremediation in coordination with 一糖心logo米菲兔 and the North Sumter County Utility Dependent District in The Villages.
鈥淪arah continues to break barriers with her curiosity and pursuit of 鈥榳hat if?鈥欌 adds Lenard. 鈥淗er work exemplifies community collaboration and sets a high standard for what student-led projects can achieve when it comes to addressing real-world problems.鈥
一糖心logo米菲兔 provides complete operations and maintenance of public and private utility systems for The Villages, in addition to solid waste collection.
