Waste Management and Recycling in Saudi Arabia: A Worked Plant Economics Example

An illustrative model of a construction and demolition waste recycling plant in Saudi Arabia, showing how gate fees, product sales and utilisation drive payback.

Waste management and recycling in Saudi Arabia are being reorganised under the National Center for Waste Management (MWAN), which licenses waste activities, sets rules for handling and disposal and pushes diversion away from landfill, with a growing role for private operators and PIF-backed recycling ventures. Construction and demolition waste is one of the largest streams because of the scale of building across the Kingdom. The worked example below uses illustrative inputs to show that a recycling plant lives or dies on how much material actually arrives at its gate.

The situation

An investor plans a construction and demolition waste recycling plant on leased land near a major city, charging gate fees to contractors who deliver waste and selling crushed, screened recycled aggregate for sub-base, backfill and landscaping uses.

Assumptions (illustrative)

• Design intake capacity: 200,000 tonnes per year.
• Assumed utilisation in a normal year: 70 per cent of capacity.
• Assumed gate fee charged to contractors: SAR 20 per tonne.
• Assumed recycled aggregate yield: 80 per cent of intake, sold at SAR 25 per tonne.
• Assumed operating costs including staff, fuel, maintenance, land rent and residue disposal: SAR 3,200,000 per year at 70 per cent utilisation.
• Assumed capital cost for crushers, screens, mobile plant, weighbridge and site works: SAR 15,000,000.

Step 1: Annual intake

200,000 tonnes multiplied by 70 per cent equals 140,000 tonnes.

Utilisation depends on how strictly the rules requiring contractors to use licensed facilities are enforced by MWAN and the municipalities.

Step 2: Gate fee revenue

140,000 tonnes multiplied by SAR 20 equals SAR 2,800,000.

Every riyal of gate fee competes with the contractor's cost of hauling to a landfill or, where enforcement is weak, dumping illegally.

Step 3: Aggregate sales

140,000 multiplied by 80 per cent equals 112,000 tonnes; 112,000 multiplied by SAR 25 equals SAR 2,800,000.

Sales depend on consultants and clients writing specifications that allow recycled aggregate, and on the price of virgin quarry material nearby.

Step 4: Operating profit

SAR 2,800,000 plus SAR 2,800,000 equals SAR 5,600,000 of revenue; minus SAR 3,200,000 of costs gives SAR 2,400,000.

A workable result at 70 per cent utilisation, before financing, Zakat or tax.

Step 5: Simple payback

SAR 15,000,000 divided by SAR 2,400,000 equals 6.25 years.

Acceptable for equipment-heavy infrastructure, provided the intake assumption holds for the whole period.

Step 6: Utilisation test

At 50 per cent: intake 100,000 tonnes; gate fees SAR 2,000,000; aggregate 80,000 tonnes worth SAR 2,000,000; revenue SAR 4,000,000. Costs are mostly fixed, assumed at SAR 2,900,000, leaving SAR 1,100,000. Payback: SAR 15,000,000 divided by SAR 1,100,000 equals about 13.6 years.

A 20-point fall in utilisation more than halves profit and more than doubles payback, because most costs do not shrink with volume.

What changes the answer

• Enforcement of waste regulations by MWAN and municipalities, which decides whether contractors pay gate fees at all.
• Specifications from consultants and public clients that accept recycled aggregate in roads, sub-base and fill.
• Haul distance from the main construction and demolition areas, since contractors avoid long trips.
• Landfill charges and the availability of cheaper disposal routes.
• Licence conditions, including environmental monitoring, dust control and residue disposal.

What the numbers tell you

• Secure feedstock agreements with large contractors, developers or municipalities before ordering equipment.
• Work with specifiers and testing labs so that recycled products are accepted in real projects.
• Locate close to construction activity and on routes trucks already use.
• Confirm licensing and environmental conditions with MWAN and the municipality before leasing land.
• Model the plant at low utilisation first; if it survives that case, the base case is credible.
