Sustainability in practice
The work is in the process.
Feedstock selection, recovery systems, thermal utilities and plant handling determine the practical impact of resin manufacturing.
Practical scope
Sustainability is a production discipline.
Specialty resin manufacturing is resource-intensive chemistry. Our approach is practical: choose renewable inputs where the formulation allows, recover water and solvent, manage heat carefully and keep material handling enclosed.

CSR
CSR records belong with the operating record.
Published CSR entries are kept as concise records with focus area, period, location, status and supporting documents where available.

Recovery before release.
Water recycling, solvent recovery, controlled heat and enclosed handling are part of the plant operating model.
-
01
Process water recovery
Condensate from esterification reactions is captured, treated and reused as process water.
-
02
Solvent recovery
Reactor solvents are distilled and returned to the process loop rather than vented.
-
03
Natural-gas thermal
Reactor jackets are heated by natural-gas-fired thermal fluid systems.
-
04
Enclosed solid handling
Flakes, beads, granules and powders are handled through enclosed conveying systems.
-
05
Effluent: none
The plants are operated around process recovery rather than effluent discharge.
-
06
Continuous monitoring
QA and EHS monitor emissions, acid value, batch temperature and residual solvent.
12 Principles of Green Chemistry
A framework tied to plant decisions.
The principles are useful when they guide a specific choice in synthesis, utilities, monitoring or handling.
Prevent waste
Process design favours conversion over rework, fewer purge cycles, fewer drum-outs of off-spec material.
Atom economy
Esterification and polyamidation routes are chosen for high atom incorporation; by-products are minimised by design.
Less hazardous synthesis
We engineer around safer reagents wherever the chemistry allows, particularly in our newer phenalkamine and adduct lines.
Safer chemicals
Our catalogue prioritises REACH-registered, non-restricted chemistry for export markets.
Safer solvents
Where solvents are required, we lean toward MTO, xylene blends and ethyl acetate, and recover them in-plant rather than vent.
Energy efficiency
Reactor sizing and run cadence are tuned for thermal efficiency; natural-gas heating cuts our carbon intensity per batch.
Renewable feedstocks
Rosin, vegetable oils, dimer fatty acids, large parts of the catalogue start from renewable raw materials.
Reduce derivatives
Protection / deprotection steps are avoided where the synthesis tolerates it.
Catalysis
Catalysed esterification and polyamide formation reduce the energy required per kg of finished resin.
Design for degradation
Renewable-feedstock chemistries inherently have a more benign end-of-life profile than petroleum analogues.
Real-time analysis
Acid value, viscosity, colour and amine value are tracked in-line, drift is caught mid-batch, not post-shipment.
Inherently safer chemistry
We invest in process design that reduces the probability and severity of a release, independent of operational discipline.
Feedstock register
Renewable inputs connected to finished grades.
Gum rosin, dimer fatty acids and vegetable oils appear across established Unikyd, UMaleic, Unigum, Unimide and PR product families.
Gum rosin

Linseed oil
Unikyd L-80 · L-100 · LR-50
Long-oil alkyds with high-gloss, deep-penetration drying profiles for architectural and industrial use.
Dehydrated castor oil (DCO)
Unikyd D-100 · DR-50 · DR-70
DCO-based long oil and rosin-modified alkyds with excellent colour stability.
Soya oil
Unikyd S 705
Non-yellowing white enamels and decorative paints, clean dry, clean colour.
Mixed vegetable fatty acids
Unikyd S 701 · CO-48 · STY-01 · S-72 · FD-60
The backbone of our short- and medium-oil alkyd line, plus our styrenated and urethane alkyds.
Dimer fatty acids
Unimide US series
Our entire polyamide-for-inks range starts from dimer fatty acids, co-solvent, alcohol-soluble and untreated-surface grades.
