This research was carried out with the aim of justifying the recycling of solid wastes in Lahijan for the first time in 1380(2001). To do this along with physical analysis of household wastes the necessary information about the daily amount of waste collection, transportation, and final disposal charges were collected.
Results indicated that Lahijan with a population of 57298, produces wastes up to 70 tonnes per day including: paper and cardboard7%, plastic 6.6%, glass 1.2% and other disintegrating matter 83.85. Their collection and landfill charges for each year was estimated at 3115881265 Rials(€ 3.11 thousands). An appropriate recycling plan can obtain profits summing up 392046515.2 Rials for paper and cardboard, 715932815.2 Rials for plastic, 6146311 Rials for metal, 6146311 Rials for glass, and 688495.4 Rials for cult. The total amount of saving could be 127160447.8 Rials (€ 12 thousands). Camparing the collection, transportation and landfill costs, as well as, environmental impact, the recycling of soild waste has a complete economic feasibility.
