Most chemical fire extinguishers need to be properly disposed of, or recycled, not tossed in the nearest dumpster or trash can.
They contain chemicals, and some are considered hazardous waste, and should not end up in a landfill. A cheap (but still pressurized) extinguisher could pose a risk to a worker, if the plastic valve gets damaged or broken during the process of transportation and handling in the waste disposal process, or at the landfill.
'Proper disposal' (or recycling) varies by city, county, or state.
