Our Story
The ocean and nature are our best friends. However, we’ve seen that much of the waste polluting them comes from packaging. So in 2023, we founded Sirsak to develop a scalable solution for packaging waste especially on those of low values to ensure that it will not be wasted.

But we can't do it alone. We need you — whether you’re in government, business, or the community — to join us in driving meaningful changes. Together, we can tackle this challenge and protect the environment we all love.
