PET Bottle Recycling Line Cost Calculator (2026 Edition)

Can You Estimate Your Real Recycling Cost Per Ton?

Most investors in PET recycling focus on machine price and capacity, but the real profit depends on one key metric:

Cost per ton of washed PET flakes (USD/ton)

This calculator-style guide helps you estimate your real operating cost step by step.

Step 1: Input Your Key Project Parameters

Before calculating, define your project conditions:

• Line capacity: ___ tons/hour

• Operation hours: ___ hours/day

• Raw material type:

• ☐ PET bottle bales (clean)

• ☐ Mixed waste bottles

• Final product requirement:

• ☐ Industrial grade flakes

• ☐ Food-grade flakes (hot wash required)

• Electricity price: ___ USD/kWh

• Water cost: ___ USD/ton

• Labor cost: ___ USD/day/operator

⚙️ Step 2: Raw Material Cost (Main Cost Driver)

Typical PET bale pricing range:

• Clean PET bottles: 180–320 USD/ton

• Mixed PET waste: 120–250 USD/ton

⚠️ Key Formula:

Raw material cost dominates 40%–70% of total cost

If your input quality is unstable, your final cost will increase sharply due to:

• Higher sorting loss

• More washing chemicals

• Increased energy consumption

⚡ Step 3: Electricity Consumption Calculator

PET washing lines consume energy in 4 main systems:

• Crusher

• Hot washing system

• Friction washer

• Dewatering & drying system

Standard consumption benchmark:

• 150 – 300 kWh per ton of PET flakes

Calculation:

Electricity Cost per ton =
kWh per ton × electricity price

Example:

• 220 kWh × $0.12 = $26.4 / ton

Step 4: Water Consumption Cost

Water usage depends on system design:

Open loop system:

• 3–5 tons water / ton PET flakes

Closed loop recycling system:

• 0.5–1.5 tons water / ton PET flakes

Calculation:

Water Cost per ton =
water usage × water price

Example:

• 1.2 tons × $0.8 = $0.96 / ton

Step 5: Labor Cost Estimation

Typical staffing:

Formula:

Labor Cost per ton =
(daily labor cost ÷ total daily output)

Example:

• $300/day ÷ 40 tons = $7.5 / ton

Step 6: Maintenance & Wear Parts

Includes:

• Crusher blades

• Screens

• Bearings

• Pumps

Standard range:

$5 – $15 per ton

Key factor:

• PVC contamination ↑ = wear cost ↑ sharply

Step 7: Chemical & Hot Washing Cost (If Applicable)

If you produce high-quality PET flakes:

• Caustic soda

• Detergent

• Heating energy

Cost range:

• $8 – $25 per ton

Step 8: Yield Loss (Hidden Cost)

Not all input becomes final product.

Typical loss:

• High quality system: 5%–8%

• Standard system: 8%–15%

Impact:

If 1 ton input → 0.88 ton output
Your real cost per ton increases proportionally

Final Formula: Total Cost per Ton PET Flakes

Total Cost =
Raw Material

• Electricity

• Water

• Labor

• Maintenance

• Chemical cost

• Loss factor

Example Full Calculation 

Assumption:

• Capacity: 3 T/H

• PET bale: $220/ton

• Electricity: 220 kWh @ $0.12

• Water: $1/ton

• Labor: $8/ton

• Maintenance: $10/ton

• Chemical: $12/ton

Result:

What This Means for Your Business

Your profit is not decided by machine price.

It is determined by:

• Raw material stability

• Energy efficiency of the line

• Washing system design

• Water recycling capability

• Automation level

Key Insight (Very Important)

Two PET recycling lines with same capacity can have 20%–35% cost difference

Main reason:

• Pre-washing efficiency

• Hot washing design

• Drying system efficiency

• PVC separation performance
