About Scrapmint

A young Indonesian collective tackling the waste crisis at scale.

Founded by students at Jakarta Intercultural School, Scrapmint connects brands, institutions, and communities to circular-economy solutions — from material recovery to bioconversion to curated sustainability events.

Founding team

Why we exist

The scale and shape of Indonesia's waste problem.

43.2M T
Total waste generated in Indonesia · 2023
67%
Leaked — open dumps, burning, waterways
70%
Growth in MSW methane emissions · 2000–2022
Composition of the waste stream · 2024
39%
Food
18%
Plastic
32%
Paper
11%
Other

Food waste is the largest fraction — which makes bioconversion the highest-leverage intervention. It touches 39% of the stream, not a niche.

The systemic gap

Why standard solutions don't scale — three structural failures.

Financing gap

Money is unstable
and insufficient

  • Annual DAK allocations not guaranteed
  • Long-term planning fragmented
  • KPBU, blended finance, EPR underdeveloped
Infrastructure gap

Facilities exist
but don't work

  • Only 538 of 922 TPS3R units functional (58%)
  • USD 12.8M public loss over 8 years
  • 127 PDU hubs across 19 of 38 provinces
Behaviour gap

Individuals generate
but don't sort

  • Households generate 50.8% of total waste
  • Most waste enters landfill mixed
  • Awareness ≠ behaviour without infrastructure

Vision

To build a generation of innovators who turn scrap into sustainable materials — and create measurable impact.

Mission

We solve waste by raising awareness and bringing innovative solutions to stakeholders — turning waste into worth.

The shift

From a linear take-make-dispose model
to a closed-loop circular system.

From · today
Linear
Take → Make → Use → Dispose
