| Tóm tắt: | Abstract Objective Globally, cities generate 1.3 billion tons of solid waste per year, amounting to a rate of 1.2 kg per person per day. Solid waste management is an important challenge to both the developed and developing countries. This study aimed to assess the willingness to pay for the improved solid waste management and associated factors among households in Injibara town, Ethiopia. Results A total of 903 household heads participated in the study. The finding indicated that 81.06% were willing to pay for the service. The average amount of money the participants would be willing to pay per month was 29.7 ETB ($1.07)). The study revealed that sex (β = 3.24, (95% CI 1.98, 4.50)), age (β = − 0.09: 95% CI − 0.19, − 0.01), educational status (β = 6.19: 95% CI 3.54, 8.84), occupation (β = 2.43: 95% CI 1.009, 3.86), amount of solid waste generated (β = 1.74: 95% CI 0.19, 3.29), distance from dump site (β = 1.58: 95% CI 0.45, 2.72), satisfaction with the existing service (β = 3.89, (95% CI 2.75, 5.06) and wealth status (β = 2.43: 95% CI 1.0, 3.86) were statistically significant. Therefore, the level of premium load should consider the amount of waste generated, wealth status and the distance from the dump site.
