As cities worldwide strive for cleaner urban environments, Green Motor Technology (GMT) is leading the charge in converting traditional diesel-powered garbage trucks to fully electric operation. This comprehensive guide explores the technical and operational aspects of converting the Hyundai HD120 garbage truck, a workhorse in municipal waste collection, to clean electric propulsion.
Why Convert Garbage Trucks to Electric?
Environmental Benefits
- Zero tailpipe emissions
- Reduced noise pollution
- Cleaner air in urban areas
Operational Advantages
- 60-70% lower energy costs
- Reduced maintenance
- Regenerative braking benefits
Municipal Benefits
- Compliance with clean air regulations
- Improved public image
- Future-proof fleet
Industry Insight: Garbage trucks are ideal candidates for electrification due to their predictable routes, frequent stop-start operation (where electric excels), and operation in dense urban areas where emissions reduction is most valuable.
