The carbon and circular-economy math behind PureSil

PureSil Mineral Silicate Paint: Sustainability Data Reference Sheet

1. Cradle-to-Gate Carbon Footprint Comparison

The following data quantifies the upfront greenhouse gas emissions from raw material extraction through manufacturing output (Cradle-to-Gate).

2. 20-Year Project Lifecycle Carbon Mathematics

This model projects the cumulative carbon footprint of a commercial project requiring an initial coating mass of 3,000 kg over a 20-year structural evaluation period.

Conventional Acrylic Paint System

  • Performance Cycle: Requires full re-application every 6–7 years due to film degradation (peeling, blistering, UV chalking).
  • Total Cycles (20 Years): 3 distinct painting cycles (Initial application at Year 1, Repaint at Year 7, Repaint at Year 14).
  • Material Consumption: $3,000 \text{ kg} \times 3 \text{ cycles} = 9,000 \text{ kg}$ total coating mass.
  • Total Carbon Cost: $9,000 \text{ kg} \times 3.0 \text{ kg CO2e/kg} =$ 27,000 kg CO2e

PureSil Mineral Silicate Paint System

  • Performance Cycle: Permanent silicification microcrystalline bond provides a 20+ year functional life.
  • Total Cycles (20 Years): 1 single application (Year 1).
  • Material Consumption: 3,000 kg total coating mass.
  • Initial Carbon Cost: $3,000 \text{ kg} \times 1.2 \text{ kg CO2e/kg} = 3,565 \text{ kg CO2e}$
  • Active Carbon Sequestration Offset: -35 kg CO2 absorbed during curing.
  • Total Net Carbon Cost: 3,530 kg CO2e

Net Environmental Avoidance

  • Net Carbon Avoided per Project: ~23.4 metric tons (23,470 kg) CO2e

3. Recycled Feedstock Composition

PureSil replaces virgin mineral fillers and synthetic binders with upcycled industrial and agricultural by-products.

  • Total Upcycled Material Content: 85% of total raw product mass
  • Feedstock Stream 1: Rice Husk Ash (RHA) — sourced as an agricultural waste product from biomass power generation, rich in amorphous silica.
  • Feedstock Stream 2: Coal Fly Ash — sourced as an industrial byproduct from regional power generation, acting as a reactive pozzolanic matrix.

4. Active Carbon Dioxide Sequestration

During the atmospheric curing phase, the liquid waterglass binder chemically reacts with ambient carbon dioxide to form an insoluble mineral structure.

  • Sequestration Rate: ~3.5 g CO2 per square metre, per coat
  • Curing Reaction Mechanism (Plain Text): M2O.3SiO2 + CO2 -> M2CO3 + 3SiO2 (where M represents the alkali metal cation Potassium)

This reaction permanently locks atmospheric carbon into the calcium silicate hydrate matrix of the wall, preventing re-emission.

5. Green-Building Certification Credit Alignment

PureSil directly contributes toward earning points under the Leadership in Energy and Environmental Design (LEED) and Indian Green Building Council (IGBC) frameworks.

6. Methodology & Standards Note

  • Assessment Boundary: Cradle-to-Gate.
  • Framework Standard: Evaluated in structural alignment with ISO 14040/14044 Life Cycle Assessment principles.
  • Audit Type: Internal lifecycle assessment (LCA) mapped across the Relic Coatings LLP production facility at MIDC Butibori, Nagpur.
