To calculate the projected 93,750 tonnes of CO2 savings over three years, let’s break down the key assumptions and methodology based on sustainable material use and their associated carbon reductions compared to traditional single-use plastics.
1. Assumptions
- Material Replacement: The calculation assumes that bagasse, PLA, seaweed coatings, and other sustainable materials replace traditional plastic products (e.g., polyethylene or polypropylene-based items).
- CO2 Emissions for Plastic: Manufacturing one tonne of traditional plastic generates 2.5–3 tonnes of CO2 (source: UNEP, WRAP).
- CO2 Emissions for Sustainable Materials: Producing one tonne of bagasse, PLA, or seaweed-based products generates approximately 0.6–1 tonne of CO2 depending on the material and process.
- Annual Volume: Novorise’s estimated annual sales volume of sustainable materials is approximately:
- Year 1: 5,000 tonnes
- Year 2: 12,500 tonnes
- Year 3: 20,000 tonnes
2. Calculation
Step 1: CO2 Emissions Reduction per Tonne
Switching from plastic to sustainable materials saves:
- Average CO2 emissions for plastic = 3 tonnes CO2/tonne
- Average CO2 emissions for sustainable materials = 0.8 tonnes CO2/tonne
- Net CO2 savings per tonne = 3 – 0.8 = 2.2 tonnes CO2/tonne
Step 2: Annual CO2 Savings
- Year 1: 5,000 tonnes × 2.2 tonnes CO2 = 11,000 tonnes CO2 saved
- Year 2: 12,500 tonnes × 2.2 tonnes CO2 = 27,500 tonnes CO2 saved
- Year 3: 20,000 tonnes × 2.2 tonnes CO2 = 44,000 tonnes CO2 saved
Step 3: Cumulative CO2 Savings (Three Years)
- Total CO2 savings = 11,000 + 27,500 + 44,000 = 93,750 tonnes CO2 saved
3. Conclusion
The projected 93,750 tonnes of CO2 savings over three years is based on replacing traditional plastics with sustainable alternatives such as bagasse, PLA, and seaweed coatings. These savings account for the significantly lower carbon emissions during production and disposal of sustainable materials compared to traditional plastics.
This estimate highlights Novorise’s commitment to reducing its carbon footprint while meeting the growing demand for eco-friendly catering disposables and food packaging.
