Testimonials: What Municipalities Say About Treatment Plant ROI

"When we first started looking at e-waste, it felt like a losing battle," admits Maria Gonzalez, Springfield's Waste Management Director. "We were paying $45 per ton to send old computers and TVs to landfills, and residents kept dropping off more—especially circuit boards, which are heavy and expensive to dispose of. Then we heard about circuit board recycling equipment that could recover metals like copper and gold. The upfront cost made us nervous: $420,000 for a mid-sized system with dry separator. But we crunched the numbers." Springfield's team projected handling 500 tons of circuit boards annually. The equipment, they learned, could extract about 15% metal by weight—translating to roughly 75 tons of recoverable metal per year. At market prices, that meant $180,000 in annual revenue from scrap sales. "We also saved $22,500 on landfill fees (500 tons x $45/ton)," Gonzalez adds. "Plus, the state gave us a $50,000 ｇｒａｎｔ for green infrastructure. Suddenly, that $420,000 investment felt manageable." The system went live in early 2023. By year-end, Springfield had processed 530 tons of circuit boards—beating projections—and revenue hit $192,000. "The dry process equipment was key," Gonzalez notes. "It uses less water than wet systems, so our utility bills stayed low, and maintenance has been minimal. We're on track to recoup the investment in under 2 years. And residents? They love that their old tech is 'paying for itself.'"

Aurora's problem wasn't just waste—it was compliance. "Our old lead-acid battery recycling facility was hitting air quality violations," says Raj Patel, Aurora's Environmental Compliance Officer. "The state was threatening fines of $10,000 per month if we didn't reduce emissions. We needed air pollution control system equipment, but the quotes were eye-watering: $650,000 for a full system with scrubbers and filters." The team weighed the options: pay fines ($120,000/year) or invest in the system. "We also realized the old setup was inefficient," Patel explains. "We were losing about 10% of recoverable lead to emissions—metal we could sell. The new air pollution control system equipment would capture that, plus avoid fines." Installation took three months, and by month four, emissions dropped by 95%. "The state lifted the violation notice, which was a huge relief," Patel says. "But the surprise was the metal recovery: we're now getting an extra 8 tons of lead per month, worth $14,000. That's $168,000 annually. Add in the $120,000 saved on fines, and we're seeing $288,000 a year in benefits. The ROI? Just over 2 years. And our community no longer complains about the smell near the facility. Priceless."

Portland has long been a leader in sustainability, but its recycling plant's water usage was a sore spot. "We were using 30,000 gallons of water daily to process wet materials—stuff like lithium-ion battery waste and scrap metal," says Thomas Lee, Portland's Sustainability Director. "Our water bills were $18,000 per month, and treating that wastewater? Another $12,000. We needed water process equipment that could recycle and treat on-site." The city invested $580,000 in a closed-loop water system, which included filters, sediment separators, and a treatment unit. "The sales rep called it a 'no-regret' upgrade, but we were still cautious," Lee laughs. "$580k is a lot for a city with competing priorities. But we projected cutting water use by 70%." The results exceeded expectations. "We're now using just 8,000 gallons daily—an 80% reduction," Lee reports. "Water bills dropped to $4,800/month, and wastewater treatment costs? Down to $3,200. That's $216,000 saved annually. Plus, the system qualifies for a 10% tax credit, which added $58,000 back to our budget. At this rate, we'll hit ROI in 2.4 years. And here's the kicker: the state awarded us $100,000 for water conservation, so we're using that to fund a public education campaign. It's a win-win-win."

"Space was our biggest issue," says James Wilson, Fort Worth's Solid Waste Superintendent. "Our landfill was filling up fast—we had 8 years of capacity left, tops. We needed to reduce the volume of scrap metal, plastic, and cardboard we were sending there. Hydraulic press machines kept popping up in our research: they compact materials into dense bales, cutting transportation costs and landfill space." Fort Worth bought two hydraulic press machines: one for metal ($180,000) and one for plastic/cardboard ($160,000). "We were moving 200 tons of loose scrap metal monthly, paying $850 per truckload. After compacting, we fit 30% more per load—so instead of 10 trucks, we used 7. That's $2,550 saved per month, or $30,600 annually," Wilson explains. "For plastic and cardboard, we went from 15 trucks to 9 per month, saving another $5,100 monthly ($61,200/year)." The machines also opened up new revenue streams. "Compacted bales are more valuable to recyclers," Wilson notes. "We used to get $120/ton for loose cardboard; now we get $180/ton for bales. That's an extra $60/ton on 300 tons monthly—$216,000 a year. Total annual benefits? $307,800. The combined investment was $340,000, so ROI was just 13 months. We're now looking at adding a hydraulic baler for textiles. This stuff pays for itself."

Boise's challenge was lithium-ion batteries—from old phones to electric vehicle (EV) packs. "We were seeing 200+ EV batteries a year, and they're dangerous to landfill—risk of fire," says Carlos Mendez, Boise's Waste Operations Manager. "We looked into li-ion battery breaking and separating equipment, which recovers cobalt, nickel, and lithium. The price tag? $750,000 for a system with 500kg/hour capacity. Sticker shock, right? But EV battery recycling is a growing market. We decided to bet on the future." The system launched in late 2022. "The first six months were slow—we were still learning," Mendez admits. "But by month seven, we were processing 40 tons of li-ion batteries monthly. The recovery rate is about 25% metals by weight, so 10 tons/month. At current market prices, that's $35,000 monthly, or $420,000 annually. We also charge residents a small fee—$10 per battery ｄｒｏｐ-off—to cover handling, which adds $24,000 a year. Total annual benefits: $444,000." Mendez says the investment is on track to pay off in 1.7 years. "But here's what no one tells you: the community loves it. EV owners feel good knowing their old batteries are recycled, not incinerated. We've even had local EV dealerships partner with us to refer customers. This didn't just improve our ROI—it made recycling a community event."
