While we not often think about it, the breakdown of matter in landfills potential produces methane and hydrogen sulfide gases. These gases present a risk of explosion (as they are both flammable) and hydrogen sulfide serves as a health hazard—potentially causing death if breathed in massive doses. Given the volatility of these two by-products of landfills, many local governments seek out better ways to monitor the potential production of these gases in their landfills. Moreover, seeing the needs of these local governments, Plexus Controls, a Canadian-owned designer and manufacturer of wireless monitoring and control products, decided to create a product for monitoring methane and hydrogen sulfide gases for landfills.
