Sustainable Waste Management: How Mulching Can Help
Here’s how one city is reducing landfill emissions and putting trash to good use.
If you’re like many of us, you’re probably conscious of the trash that you send to the landfill – especially all the stuff that doesn’t break down quickly like plastics and metals. But you may not know that organic trash — stuff that decomposes — also makes a big impact on the environment and it’s a challenge for city Waste Management Departments.
Landfills Create Greenhouse Gases
Approximately 30-40 percent of the average landfill is taken up by organic trash – yard waste, brush, food scraps, etc. When it decomposes, it releases methane into the atmosphere, which is more than 25 times as potent as a greenhouse gas than carbon dioxide. Globally, landfills release around 12 percent of the total methane emissions. While that sounds bleak, there is good news: methane doesn’t live nearly as long in the atmosphere as CO2 (12 years vs 100-300 years). That means that if we reduce methane emissions, we’ll see a faster benefit in terms of reduced greenhouse gases.
Making Trash Useful
There are many ways that Waste Management Departments reduce greenhouse emissions, including methane capture and tunnel composting. The City of San Antonio is trying to keep much of the organic waste out of the landfill all together and, instead, recycle it into something useful – mulch. The key: a super heavy-duty grinder.
The city uses a HogZilla tub grinder powered by a Cat® C32 engine. It’s got the torque, power, and reliability they need to create mulch out of the nearly 100,000 tons of brush, Christmas trees and other debris that would have otherwise ended up rotting in a landfill. The city provides the mulch to residents at low cost, or sometimes for free. So, instead of creating emissions, all that garbage-turned-mulch is making landscaping around the city more beautiful.
This is just one way that Cat powered grinders help our communities improve the environment. Check out this story about how our customers are helping communities make the switch to solar energy.
The City of San Antonio’s Solid Waste Management Department serves more than 360,000 customers. They depend on over 800 pieces of equipment to keep their operation running safely and efficiently.
When they were tasked with turning more than 100,000 tons of organic waste into mulch, they chose a HogZilla tub grinder powered by a Cat C32 engine.
By grinding up all that organic matter, the City of San Antonio can produce enough mulch to cover 8,300+ football fields.
Then they’re able to provide this mulch to residents for cheap — or sometimes even free — making landscaping around the city even more beautiful.
