The transportation sector

In Québec, the transportation sector emits the most greenhouse gas (GHG), at 47.4% of total emissions.1 As key players in the transportation sector, municipalities and waste collection businesses can take an active role in developing sustainable energy solutions.

Compressed natural gas, an attractive alernative

Compressed natural gas (CNG) is an attractive alternative fuel for powering waste collection trucks. The North American market is gravitating increasingly toward this solution: 60% of waste collection trucks sold in the United States are now fuelled by CNG!1

Why choose compressed natural gas?

The high energy consumption of collection trucks due to their frequent stops and starts, combined with the short distances they travel, make them ideal candidates for CNG.

More economical                                            More respectful
  • Up to 30% more economical
  • More stable fuel costs
  • Lower maintenance costs (no urea)
  • 18% less GHG
  • Pure air: major reduction of SO2, NO2 and fine particulates
  • Noise level similar to a small car 

These aspects are not only beneficial to truck owners, they also ensure greater social acceptability.

Inspiring leaders

Québec is now targeting a 37.5% reduction in GHG emissions from 1990 levels. To set an example and achieve this objective, many municipalities and waste collection businesses are now opting for CNG.

A first in the Eastern Townships

Five new dump trucks belonging to the company Sani-Estrie will now be used to collect waste in Magog. These new strategic choices are aligned with the city's shift to environmental awareness.

A sustainable and profitable choice

Switching to CNG is necessarily part of a sustainable development initiative. This choice must not only have a positive impact on the environment, it must also be profitable. Depending on the fleet profile, the savings achieved by switching to CNG can allow municipalities and businesses to cut their fuel costs and invest more in other projects.

Savings are therefore proportional to fleet size. Generally, the installation of a private refuelling station requires that at least 10 collection trucks be on CNG. For fewer than 10 trucks, the use of a public refuelling station is recommended in order to generate enviable profitability.

Simple refuelling

The CNG refuelling process is similar to that of traditional fuels. Depending on the fleet's needs, refuelling can be done fast or slowly, during off hours. No specific competency card is required to carry out refuelling.

Biomethane:  A unifying project

Biomethane is a 100% renewable, carbon-neutral, natural gas produced from organic waste collected through brown bin programs or from agricultural enterprises. Through the biomethanization process, the biogases from this waste are recovered and turned into clean energy that can be transformed into CNG.

Fuelling collection trucks with biomethane is a fantastic project involving the citizen, the municipality and the waste collection company.


2 Baseline consumption level of 2,000,000 litres of diesel divided among 3 subcontractors ≈ 650,000 L and 18 trucks per subcontractor. Annual baseline consumption level of 35,000 litres of diesel per truck. Class 8 trucks with Cummins ISL-G engine (100% CNG). Surcharge for CNG version: $50,000 (90 diesel gallon equivalent tanks) + trucking energy-conservation subsidy (‑$15,000). Price of diesel @ $1.00/litre. Price of CNG includes: commodity, Gaz Métro services, refuelling equipment depreciation, maintenance and electricity. Private refuelling: construction of an on-site CNG filling station + garage upgrade; slow fill (8 hours for all trucks). Public refuelling: use of a third-party-operated CNG filling station + garage upgrade; fast fill (15 minutes per truck).

The savings calculations provided in this study are estimates and are provided for information purposes only.
