Конвертор со влијание од пластика во океан

The Plastic to Ocean Impact Converter translates your weekly single-use plastic consumption — water bottles, grocery bags, takeout containers, straws and utensils — into estimated annual ocean-bound plastic weight, CO₂ footprint from production, and a qualitative impact tier (Low / Moderate / High / Severe). The calculation uses typical per-item weights from packaging industry data (PET water bottle full ≈ 25 g; thin grocery bag ≈ 6 g; takeout clamshell ≈ 30 g; plastic straw/utensil ≈ 2 g) multiplied by an ocean-bound rate. Ocean-bound rate varies dramatically by region. The global average is roughly 2% of all plastic waste (per Ocean Conservancy and Jambeck et al. 2015 research published in Science), but coastal regions with weak waste infrastructure can reach 10–20%. Wealthy nations with strong waste management (US, EU, Japan) sit closer to 0.5–1.5%; Southeast Asia and parts of West Africa contribute disproportionately due to leakage from landfills, illegal dumping, and stormwater runoff. The calculator defaults to the global 2% figure but lets you adjust for regional context. CO₂ footprint reflects greenhouse gas emissions from plastic production: petroleum extraction, refining, polymerization, manufacturing, and transport. Industry averages run roughly 6 kg CO₂ per kg of plastic produced (varies by resin type: PET ≈ 2.7, PP ≈ 1.9, PS ≈ 3.4, mixed average closer to 6 including end-of-life). Plastic production emits roughly 2 gigatons CO₂e annually — about 4% of global emissions, similar to global aviation. What the impact tiers mean: Low Impact (< 4 kg annual plastic) is achievable with reusable bottle + reusable bags + minimal takeout. Moderate (4–12 kg) is typical conscientious-but-imperfect household. High Impact (12–25 kg) suggests heavy single-use reliance — daily bottled water, frequent takeout, ungrouped grocery trips. Severe (> 25 kg) is unusually high consumption — typically commercial use leaking into personal estimates, or households without any reusable substitution. Most households who track usage discover they're in the Moderate-to-High range and can cut 60–80% with two habit changes: reusable water bottle and reusable grocery totes.

1. 1Step 1 — Count single-use plastic items used in a typical week across four categories
2. 2Step 2 — Calculator multiplies counts by typical per-item weights to estimate total weekly plastic mass
3. 3Step 3 — Annualizes by multiplying weekly mass × 52 weeks
4. 4Step 4 — Applies ocean-bound rate (2% global default; adjustable for regional context) to estimate ocean-bound portion
5. 5Step 5 — Computes CO₂ footprint at ~6 kg CO₂ per kg plastic from production lifecycle data
6. 6Step 6 — Assigns impact tier: Low (<4 kg), Moderate (4–12 kg), High (12–25 kg), Severe (>25 kg)
7. 7Step 7 — Output displays annual mass, ocean equivalent, CO₂ tonnes, and recommended habit changes

• !Underestimating bottle weight — a 500mL PET water bottle is ~20–30 g full including label and cap
• !Forgetting food packaging beyond takeout (yogurt cups, granola bar wrappers, frozen meal trays)
• !Overcounting recycling effectiveness — most curbside plastic is downcycled or exported, not truly recycled
• !Comparing reusable totes incorrectly — they only beat plastic bags after ~100+ reuses depending on material
• !Ignoring microplastics from synthetic clothing and tire wear (separate but significant categories)
