Evaluation of the environmental effects of "Khakab" construction waste recycling plant using the Iranian Leopold matrix method in EIA+ software (Case study: debris recycling plant in Abali landfill)

The recycling process of industrial wastewater leaves pollution that is evident in the process of factories producing recycled sand. This research has investigated the environmental effects of construction debris recycling in sand recycling factories.

The two phases of operation and implementation of the factory construction plan were considered as the main phases of the current research. Therefore, 13 micro-activities and 23 environmental parameters were identified and the results were analyzed in EIA+ software using the Iranian Leopold matrix method and discussed based on the results.

Three micro-activities include washing fine sand through a washing machine with a score of -3.6, converting concrete pieces and large boulders into smaller pieces and transferring them to a jaw crusher with a score of -2.8 and transferring the remaining The sewage produced by the washing machine has had the most negative effects on the depot pond with a score of -2.7. The three micro-activities of creating green spaces with a score of +2.2, selling products with a score of +0.9, and hiring employees with a score of +0.5 have the most positive effects on the environment.

Considering the positive effect on the economy, increasing the green space in the region, job creation, and also reducing the increasing amount of scum accumulated in Abali pit, the construction and operation of the factory is evaluated as a positive activity, but considering the destructive effects of the environment. its biological, it is necessary to consider alternative solutions to adjust its environmental effects.
