Todd Dunderdale Speaks At USCC Conference About Compost Contamination

Most commercial composters understand firsthand the challenges that come with removing contaminants from compost. These challenges can range from development of a successful, ongoing contaminant removal process to navigating the various regulations that dictate how materials are to be recycled or disposed of.

The Problem With Compost Contamination

“When it comes to contamination removal, some composters believe that one machine will fix everything and then all contamination problems will go away,” says Todd Dunderdale, Certified Compost Professional (CCP™) and Western Senior Area Sales Manager of Viably (formerly Komptech Americas.) “However, clean compost is not a one-step process. Every time compost is touched within the process, there’s either an opportunity to remove contaminants or make the contamination problem worse.”

Thanks to advancements in composting technology and industry-wide focus on compost education, organics waste recycling professionals are seeing new opportunities to tackle contamination while also streamlining processes.

“Compost contamination is an ongoing battle that must be fought at every step of the process. There is no single answer or solution. We also can’t leave the problem for composters, haulers or recyclers to solve. It takes all of us to combat contamination,” says Dunderdale.

Looking to the Industry Experts

This year at Virtual COMPOST2021, the US Composting Council’s annual conference and trade show, Todd Dunderdale will deliver a live presentation on “Contamination Removal From Compost”. Attendees of COMPOST2021 can watch Todd’s presentation online on Wednesday, January 27 from 3:00pm–4:15pm EST.

“In my presentation I will be discussing the overall process of removing compost contaminants and the best composting practices and equipment to support that process,” says Todd Dunderdale. “Once composters identify the contamination issues they’re facing, we can address how contaminants are getting into their compost and work to prevent it from happening.”
