Our Commitment

We make the batteries.
We take them back.

A battery manufacturer sits at the centre of Nepal's energy transition — enabling solar homes in rural hills and electric fleets in city centres. That responsibility doesn't end at the sale. Kulayan runs take-back recycling, supports clean transport, and holds itself to responsible production standards at every stage.
