Galvanizing plant feasibility: critical control points from site selection to the environmental permit

A galvanizing plant involves the use of hazardous chemicals. Not every industrially zoned parcel is suitable for the galvanizing process. The zoning plan (bölge planı — area/district plan) must have designated the site as a special industrial area or granted heavy-industry permission.

Neighbouring land uses are critical: if there is a nearby residential area, school, hospital or food-production facility, the process permit may be refused or additional measures may be required.

The acidic wastewater of the galvanizing process requires dedicated treatment. While a facility located within an organized industrial zone (OSB — organize sanayi bölgesi) can make use of the OSB's central treatment plant, in a standalone facility the investor must build their own treatment plant.

For air emissions, the stack filter, the enclosed-bath system and ventilation management must be resolved at the planning stage.

Facilities involving chemical processes, such as galvanizing, may be subject to the Environmental Impact Assessment (ÇED — Çevresel Etki Değerlendirmesi) process depending on their capacity. The difference between a "ÇED Not Required" decision and a "ÇED Favourable" decision directly determines the investment timeline in terms of both duration and cost.

The permitting process is not a single application but a chain of interdependent steps: the environmental permit, the waste declaration, the hazardous-substance use permit and, where necessary, the non-sanitary establishment (GSM — Gayrisıhhi Müessese) licence. If any one of these steps is missing, the facility cannot in practice begin production. The most common mistake investors make is to start construction before clarifying the permit timeline.

For this reason, in a galvanizing investment the question "is the site suitable?" is just as critical as the question "is the permit timeline aligned with the cash flow?" A delay in the permit increases the financing burden of an investment made in a facility that is not operating.

The storage of the zinc bath, acid tanks and auxiliary chemicals must be designed around leak-tightness, secondary containment (bund) and fire/spill scenarios. This infrastructure is not a detail added later; it is the core of the site and building plan.

Occupational health and safety is intertwined with environmental legislation: worker exposure, emergency shower stations, ventilation and waste segregation are all planned together. A feasibility study that skips this layer carries the risk of a shutdown during inspection.

In practice, the decision becomes clear through the following questions: Does the parcel's zoning permit this process? Can the wastewater be connected to the OSB's central treatment plant, or is a standalone treatment plant required? How long is the permit timeline, and once that period is reflected in the financing, does the feasibility still hold up?

In the Lizaz Emlak approach, heavy-process facilities such as galvanizing plants are evaluated by reading the engineering and real-estate layers together. The goal is to identify in advance a location that is compatible with the process and has a clear permitting path, rather than committing to a parcel that looks cheap but will never obtain a permit.
