Plastic Recycling Value Calculator
Estimate the market value of a batch of recyclable plastic by resin type. Helps households, businesses, and scrap collectors compare returns across plastic grades.
About this calculator
The calculator estimates plastic recycling value using: Value = weight × baseRate(plasticType) × condition × marketRate. Each plastic resin type (identified by its SPI resin code 1–7) has a different base rate per pound: PET (#1) at $0.32, HDPE (#2) at $0.28, PVC (#3) at $0.15, LDPE (#4) at $0.22, PP (#5) at $0.25, and other resins (#6+) at $0.18. These base rates reflect typical U.S. commodity market prices for clean, sorted plastic. The condition multiplier (ranging from 0 to 1) accounts for contamination, moisture, or mixed-resin content that reduces buyback value. The marketRate multiplier adjusts for local or seasonal price variation—markets in regions with strong export demand or nearby reclamation facilities may pay significantly above the national average base rate.
How to use
You have 200 lbs of HDPE (#2) plastic in good condition (condition multiplier = 0.90) and your local market pays 10% above average (marketRate = 1.10). Step 1: Identify base rate for plastic type #2: $0.28/lb. Step 2: Apply weight: 200 × $0.28 = $56.00. Step 3: Apply condition multiplier: $56.00 × 0.90 = $50.40. Step 4: Apply market rate: $50.40 × 1.10 = $55.44. Your 200 lbs of HDPE plastic is worth approximately $55.44 under current local market conditions.
Frequently asked questions
Which plastic resin type has the highest recycling value per pound?
PET (#1), used in beverage bottles and food containers, typically commands the highest base recycling value among common resins, largely because it has well-established collection infrastructure and strong demand from textile and packaging manufacturers. HDPE (#2), used in milk jugs and detergent bottles, is a close second due to its wide range of end-market applications. PVC (#3) consistently receives the lowest offers because of chlorine content that complicates reprocessing. Market prices fluctuate with oil prices, export demand, and virgin resin production costs, so checking current local rates is essential for accurate valuations.
How does plastic contamination affect recycling buyback prices?
Contamination—including food residue, labels, mixed resins, or moisture—directly reduces the usable yield a reclaimer can extract from a bale of plastic. Heavily contaminated loads may be rejected outright or accepted at steep discounts of 30–50% below clean-material prices. Rinsing containers, removing caps of a different resin type, and keeping loads sorted by resin code are the most effective ways to maximize the condition multiplier and therefore the value this calculator returns. Reclamation facilities increasingly use near-infrared (NIR) sorting to detect contamination, so even small amounts of wrong-resin material can downgrade an entire bale.
Why do local market multipliers vary so much for plastic recycling prices?
Plastic recycling prices are highly localized because transportation costs make it uneconomical to ship low-value materials long distances. Regions near active reclamation facilities or export ports tend to offer higher prices because buyers compete for feedstock. Conversely, rural areas far from processing infrastructure may offer prices well below the national average or have no local buyers at all for certain resin types. Global factors also matter: when China restricted plastic imports under its 2018 National Sword policy, U.S. domestic prices collapsed for many resins. Using the marketRate multiplier lets you calibrate the calculator's base rates to your specific geography and market conditions.
