Energy Efficiency of Fuel in Segregated Waste Management at Greater Jerash Municipality
The Greater Jerash Municipality (MedCities member city) is located 48 km north of the capital Amman, with an area of 160 km2. Solid waste management in Jerash municipality is considered one of the most important challenges for the city, due to the increase in population, urban expansion, the Syrian refugee crisis, and the rise in fuel prices.
The annual cost of fuel for vehicles working to collect waste for 2019 and 2020 was respectively 166,307 Jordanian Dinars (JD) and 172,723 JD. This constitutes a financial burden on the municipal budget. The municipality worked to find solutions to reduce the high cost of transporting waste from the municipality’s areas to the Ekidar landfill, which is 70 km away from the municipality area.
Challenges addressed
Diesel demand for trucks covering long distances to deliver waste to the Ekidar landfill was consuming over 30% of the municipality budget. The decision to acquire more sustainable vehicles and optimizing collection routes helped to decrease this annual expense by using self-produced renewable energy
Main objectives
- Reduction of fuel costs in waste collection and transfer.
- Introduction of sustainable vehicles supplied by self-produced renewable energy to reduce the annual expenditure for diesel.

Project description
The project is based on the optimization of waste collection by introducing electric trucks supplied by energy produced from an on-site solar PV system that has been dimensioned to cover the annual electricity needs for the service buildings and the waste transportation.
Besides, the project planned both to analyse the routes of waste trucks to improve the waste collection system and build a warehouse dedicated to waste management to facilitate the transfer.
The mentioned actions are expected to reduce costs and environmental impacts of the waste management system in Jerash.
Impact and results
- The waste truck consumes 22-25 litres of fuel per shift. It is expected to save 40% of fuel costs when applying the route optimization, as the distance travelled is reduced by half.
- The station expansions and the purchase of electric vehicles for waste collection will have a direct benefit of reducing the cost of diesel quantity by 260,000 litres annually approximately. Based on the average cost of diesel during the first 9 months in 2021 (0.56JD/Liter) in Jordan, the annual reduction in the cost for diesel is expected to be 175,000 JD.
- It is estimated that the annual emission reductions in CO2 due to diesel and electricity savings are 785 tonnes of CO2. The lifetime CO2 emission reduction is close to 19,500 MT CO2.
- The reduction in transportation and the use of electric trucks will lead to an associated reduction in operation and maintenance cost of the waste management fleet.
