Survey of processes and emissions for a metal coating plant

As part of the terms of a business license, business owners are sometimes required to submit a survey of processes and emissions related to air quality to the Ministry of Environment The purpose of the survey is to detail all the different production processes that take place in the factory, which constitute a potential for the emission of pollutants into the air.

The survey details the types and quantities of pollutants emitted into the air as a result of the production activities In the factory, along with detailing the raw materials used in the production processes that are a source of emission.


In the current project, we conducted a process and emissions survey for a metal coating and painting plant. The factory receives raw metal parts (steel or aluminum) and passes them through several stages that include polishing, immersion in treatment baths and painting.

During the preparation of the survey, all stages of the production process were examined and described, during which there may be emissions of pollutants into the air. In addition, all the emissions into the air, focal and non-focal, the facilities for treating the emissions existing in the factory, the waste, the wastewater, and the electricity and water consumption data were described. Also, the factory area and the sensitive public receptors nearby, such as gardens and schools, within a radius of 1.5 km, were carefully examined; and the environmental effects that could be a nuisance, such as odors and air pollution, were described.


During the preparation of the survey, a tour of the factory and meetings with the management team and employees were carried out, and environmental advice was given in accordance with the requirements of the authorities and regarding the improvement and optimization of the processes carried out in the factory, both economically and environmentally.

Collecting the large amount of information from the plant is painstaking and meticulous work, and requires full cooperation and ongoing contact with the plant's staff, in order to be precise about the processes and their environmental consequences. Among other things, technical data were collected regarding the plant, raw materials (names and quantities), pollutant emissions into the air from chimneys, wastewater data and water and electricity consumption. Calculations of emissions from the non-focal sources (other than via chimneys) were carried out by us based on many data such as working hours and all the available information regarding the raw materials. Non-focal emissions in a factory of this type are a complicated and complex calculation, because there are many potential focal points for these emissions, originating from volatile substances from the treatment baths, the dyeing stations, and other production processes.


In addition to the extensive and complicated work on a survey of this type, in which all the production processes and emissions of the factory are rigorously examined, this is an excellent opportunity to improve the accuracy and precision of the various technologies and processes in the factory, and to optimize the business economically and environmentally. Therefore, it is of great importance for the proper management of the project by an environmental consulting company that specializes in the field.

The Sutok company, which has extensive experience in consulting, planning and managing environmental projects, and specializes in finding customized solutions for managing waste, wastewater and improving processes. Sutok has the knowledge, connections and experience in finding optimal collaborations with the largest planning, consulting and waste treatment companies in the world. In this way, we enable our customers to turn environmental challenges, which sometimes involve financial expenses, into profit.
