Reagents and high-purity lab chemicals: Emissions
Glass, cold chains and air freight multiply the footprint
What this tab covers The greenhouse-gas footprint per tonne, split by lifecycle phase (feedstock, production, movement, use, end of life), the global total, other environmental impacts, levers and low-carbon routes, India's position, and where the investment opportunity lies.Per kg of packed reagent, cradle-to-gate. Intensity: indicative. Global total: not published.
Share of footprint by lifecycle phase
Feedstock 25% Production / process 45% Movement 30%Footprint by lifecycle phase
| Phase | Intensity | Share | Main sources of emissions | Notes | Source |
|---|---|---|---|---|---|
| Feedstock | as for the bulk chemical (see chemical tiles) | 25% | bulk solvents, acids and salts | indicative split | |
| Production / process | not published | 45% | repeated distillation and purification, cleanrooms, QC testing, glass and plastic packaging | packaging can outweigh the chemical for small packs (indicative) | indicative split |
| Movement | not published | 30% | air freight, couriers and dry ice cold chain | indicative split | |
| Use | small | – | fume hood energy and solvent evaporation in labs | labs use three to ten times more energy per square metre than offices (indicative) | indicative |
| End of life | not published | – | incineration of spent solvents and hazardous lab waste | indicative |
Other environmental impacts
Hazardous waste from labs, solvent emissions, plastic consumables and packaging waste.
Levers to cut emissions
- Solvent recycling and take-back programmes
- Greener solvent substitutions (e.g. ethanol for acetonitrile in some HPLC methods)
- Larger packs and bulk delivery
- Sea instead of air freight; less dry ice
- Miniaturised and automated assays
India
Indian reagent makers are small and private and do not publish emissions in the sources used.
Emission figures are indicative global averages from the life-cycle studies named; actual footprints vary widely by site, energy mix and method.Low-carbon routes
| Route | Intensity | Cost premium | Status | Source |
|---|---|---|---|---|
| Lab solvent recovery and reuse | avoids new solvent production and incineration (indicative) | equipment and validation | used in some pharma QC labs (indicative) | indicative |
