Indori Green Coriander Powder, 1 Kg, Packet

1 — Executive summary (headline)

Using conservative, literature-anchored assumptions for farming, drying, milling, packaging and road transport, the estimated cradle → distribution greenhouse-gas emissions for 1 kg of Indori Green Coriander Powder are ≈ 2.484 kg CO₂-eq per kg under the assumptions described below. This is a transparent, reproducible estimate — replace any assumption with measured data and I will re-run the math. smart-freight-centre-media.s3.amazonaws.com+4Central Electricity Authority+4ScienceDirect+4

2 — System boundary & functional unit

• Functional unit: 1 kg retail-ready dried & powdered green coriander (cilantro) leaves.

• System boundary (cradle → distribution):

  1. Agriculture (growing, irrigation, fertiliser, fuel) for coriander leaves;

  2. Post-harvest handling and drying (dehydration of fresh leaves);

  3. Grinding / milling to powder and blending;

  4. Primary packaging (retail pouch — embodied impacts only);

  5. Road transport from farm → mill → distribution centre.

• Excluded: retail use, consumer transport, end-of-life treatments beyond embodied packaging.

3 — Key data sources & load-bearing parameters (and why)

(Top inputs that drive the result — citations follow each.)

1. Grid electricity emission factor (India): 0.716 kg CO₂ / kWh (CEA national baseline FY2022–23). This is the standard grid EF used in many Indian product LCAs. Central Electricity Authority

2. Drying energy for coriander leaves: coriander leaf drying is technology-sensitive (sun, solar tunnel, indirect solar, forced hot-air). Studies show a wide range of drying behaviour and specific energy; we use a moderate assisted-drying value of 1.0 kWh per kg dried product (choice explained below). See experimental studies on coriander leaf drying and solar/indirect dryers. ScienceDirect+2ResearchGate+2

3. Grinding / milling energy: herb leaf powders typically need less size reduction than seeds; we use 0.15 kWh per kg as a representative milling value for leafy herb powders (literature for fine grinding shows values across a range — this is a moderate, industry-reasonable number). PMC+1

4. Packaging: assume 0.03 kg (30 g) plastic per kg product (mono PE pouch equivalent), with PE embodied emissions 2.6 kg CO₂e per kg plastic (cradle-to-gate typical). ScienceDirect

5. Road freight: 0.33 kg CO₂ / tonne-km (representative India road freight factor) and total distance = 250 km (50 km farm→mill + 200 km mill→DC). Use Smart Freight / TERI guidance for India freight factors. smart-freight-centre-media.s3.amazonaws.com+1

6. Agriculture / upstream (lumped): leafy herb production varies with irrigation and inputs. For a conservative, moderate baseline we use 1.50 kg CO₂-eq per kg finished dried powder (this lumps fertiliser, fuel, soil N₂O, irrigation and primary handling). See coriander production LCA studies showing irrigated systems are higher; dryland systems are lower. atic.razi.ac.ir+1

Notes on choices: coriander leaves are high-moisture; drying is usually the major processing energy item for leaf powders, but solar tunnel / indirect solar dryers can reduce fossil energy needs. Because the literature reports wide SECs depending on dryer type, I explicitly show sensitivity below. ScienceDirect+1

4 — Inventory (assumptions, per 1 kg finished product)

• Agriculture / upstream = 1.500000 kg CO₂e / kg

• Grinding energy = 0.150 kWh / kg

• Drying energy = 1.000 kWh / kg (assisted/hybrid dryer; solar-assisted would be lower)

• Electricity EF = 0.716 kg CO₂ / kWh (India grid) Central Electricity Authority

• Packaging = 0.03 kg PE / kg product; PE EF = 2.6 kg CO₂e / kg. ScienceDirect

• Transport = 250 km total; road EF = 0.33 kg CO₂ / t-km. smart-freight-centre-media.s3.amazonaws.com

5 — Digit-by-digit GHG calculation (1 kg basis)

Step A — Processing (electricity) emissions

1. Grinding emissions = grinding_kWh × grid_EF
   = 0.150 kWh/kg × 0.716 kgCO₂/kWh
   = 0.150 × 0.716
   Calculation: (0.150 × 0.700) + (0.150 × 0.016) = 0.105000 + 0.002400 = 0.107400 kg CO₂e / kg. PMC

2. Drying emissions = drying_kWh × grid_EF
   = 1.000 kWh/kg × 0.716 kgCO₂/kWh
   = 1.000 × 0.716 = 0.716000 kg CO₂e / kg. ScienceDirect

Processing subtotal = 0.107400 + 0.716000 = 0.823400 kg CO₂e / kg.

Step B — Packaging emissions

Packaging = 0.030 kg plastic/kg × 2.6 kgCO₂/kg plastic
= 0.030 × 2.6 = (0.03 × 2.0) + (0.03 × 0.6) = 0.060000 + 0.018000 = 0.078000 kg CO₂e / kg. ScienceDirect

Step C — Transport emissions

Road emissions = 0.33 kgCO₂ / t-km × (1 kg = 0.001 t) × 250 km
= 0.33 × 0.001 × 250 = 0.33 × 0.25 = 0.082500 kg CO₂e / kg. smart-freight-centre-media.s3.amazonaws.com

Step D — Agriculture / upstream

Assumed agriculture = 1.500000 kg CO₂e / kg. atic.razi.ac.ir

Step E — Total (sum all components)

Add stepwise (4 decimal places shown where relevant):

1. Agriculture + Processing = 1.500000 + 0.823400 = 2.323400

2. • Packaging = 2.323400 + 0.078000 = 2.401400

3. • Transport = 2.401400 + 0.082500 = 2.483900

TOTAL ≈ 2.484 kg CO₂-eq per kg Indori Green Coriander Powder (cradle → distribution). (Exact sum = 2.483900 kg CO₂e/kg; rounded = 2.484 kg CO₂e/kg.)

6 — Contribution breakdown (percent shares)

(using the rounded totals above)

• Agriculture / upstream: 1.50 / 2.484 = 60.4%

• Processing (grinding + drying): 0.8234 / 2.484 = 33.2%

• Packaging: 0.078 / 2.484 = 3.1%

• Transport: 0.0825 / 2.484 = 3.3%

Takeaway: Farming (inputs & irrigation) is the dominant source, with processing (drying) the second largest — typical for leafy herb powders.

7 — Sensitivity & uncertainty (short — swap one assumption at a time)

1. Drying energy (high): If drying SEC = 3.0 kWh/kg (forced industrial dehydration), drying emissions = 3.0 × 0.716 = 2.148 kg CO₂/kg → processing subtotal becomes 2.2554 kg → new total ≈ 3.833 kg CO₂e/kg.
   Conclusion: inefficient electric drying can more than double the product footprint. PMC

2. Drying energy (low / solar): If drying is solar-assisted and grid electric input ≈ 0.0 kWh/kg (or negligible), drying emissions → 0; processing subtotal becomes 0.1074 kg → total ≈ 1.6909 kg CO₂e/kg.
   Conclusion: switching to hygienic solar/indirect solar drying is high-leverage. ResearchGate+1

3. Agriculture (higher irrigation / inputs): if farm upstream is 2.5 kg CO₂e/kg (irrigated, input-intensive), total → 3.4839 kg CO₂e/kg. If farm upstream is lower 1.0 kg/kg (very low-input), total → 1.9839 kg CO₂e/kg.
   Conclusion: supplier agronomy and irrigation regime strongly affect the footprint. atic.razi.ac.ir

4. Mill powered by renewables: if processing electricity is replaced by onsite solar (grid EF → 0 for processing), processing emissions drop to 0.000 and total → 1.6609 kg CO₂e/kg (with agriculture 1.5). Big win. Central Electricity Authority

8 — Other sustainability indicators (brief)

• Water footprint: coriander leaf irrigation (blue water) is key — irrigated systems have much higher energy & water intensity than rainfed. Collect supplier irrigation data for water footprinting. atic.razi.ac.ir

• Quality & losses: poor drying/storage increases spoilage & rejects (wastes), increasing per-kg footprint — good drying & moisture control reduce waste and emissions per kg delivered. ScienceDirect

• Pesticide & residue risk: leafy herbs are often subject to residue concerns; Good Agricultural Practices (GAP) help reduce chemical inputs and market rejections. ResearchGate

9 — Practical mitigation recommendations (priority list)

1. Source low-input / rainfed suppliers where feasible or incentivize improved nutrient management to lower farm-stage emissions (biggest single lever). atic.razi.ac.ir

2. Adopt hygienic solar / indirect solar / hybrid dryers for coriander leaves to cut fossil energy for drying. Target drying SEC ≤ 0.5–1.0 kWh/kg effective grid input. ResearchGate+1

3. Switch mill electricity to renewables (onsite rooftop PV or green tariff) to drive processing emissions toward zero quickly. Central Electricity Authority

4. Optimize packaging: reduce pouch grams, use high-PCR PE or mono-material recyclable pouches to lower embodied emissions and improve circularity. ScienceDirect

5. Logistics & consolidation: improve truck fill factor, consolidate shipments, and evaluate rail for long legs where available. Use route planning to reduce empty backhauls. smart-freight-centre-media.s3.amazonaws.com
