Week Case Study Title Industry Segment Problem Expected Solution Approach
1 "Shade mismatch in consecutive batches" Paint (automotive) Same formula, different shade due to dispersion variation Check milling time, particle size, raw material lot variation
2 "Reactive dye effluent color exceeds ZDHC limit" Textile dyeing High color in ETP outlet despite treatment Low-salt dye + ozone/adsorption polishing
3 "Pigment settling in ink during storage" Printing ink Poor dispersion stability Adjust wetting agent, grind to finer particle size
4 "High cost of organic pigment – losing tender" Industrial coatings Competitor 18% cheaper Partial replacement with hybrid inorganic-organic pigment
5 "Vat dye reduction failure on jigger" Textile (denim) Inconsistent color yield Check hydrosulphite dosing, air ingress, temperature control
6 "Yellowing of white paint on curing" Decorative paint Unsightly customer complaint Change TiO₂ grade or add UV stabilizer
7 "Disperse dye staining on polyester-spandex" Synthetic textile Poor fastness to rubbing Optimize reduction clearing cycle
8 "Low tinting strength in yellow pigment batch" Pigment manufacturing 15% weaker than standard Check reaction pH, drying temperature, crystal form
9 "Foaming in pigment dispersion during grinding" Ink & coating Production slowdown Add defoamer, change recirculation rate
10 "Effluent sludge disposal cost too high" Dye intermediate plant ₹50/kg disposal cost Dewater + use as construction block filler
11 "Digital shade matching gives 3 different results from 3 instruments" Quality lab Calibration drift Single master instrument, regular ceramic tile calibration
12 "Customer demands GOTS-approved but cheap black colorant" Sustainable textiles Conflicting requirements Use iron-based black + bio-mordant instead of azo black
Instructor guide: Each case study ends with a one-page solution template – problem, root cause, 3 solutions (low/medium/high cost), recommendation.
