About RennoWaste

We are turning agricultural waste into the materials that industry runs on cleanly, completely, and at scale. RennoWaste builds zero-waste biorefineries that extract every unit of value from crop residues, converting what was once burned in fields into high-performance industrial materials. We are a small, driven team moving fast from prototype to production, and every person who joins shapes what we build next.

About the role

This is a hands-on, full-time production lab position. You will work alongside our scientists, executing formulations, running daily reactions, and maintaining the analytical discipline our process depends on. This is not a theoretical research role: you will be responsible for your own batches from early on.

Duration and compensation

- 6-month full-time paid internship
- High-performing interns may be offered a full time Junior Chemist position at the end of the internship

What you will do

Formulation and batch work

- Follow formulation sheets precisely: weigh, mix, and sequence ingredients as specified
- Prepare batches at bench and kilo-lab scale per SOPs
- Record batch entries accurately: quantities, observations, deviations, and yield outcomes
- Reproduce formulations consistently across multiple trial runs

Daily lab reactions





- Conduct routine titrations, pH checks, viscosity measurements, and moisture analysis
- Assist in condensation and crosslinking reactions under controlled conditions
- Support solvent extraction, filtration, and lignin fractionation operations
- Maintain daily reaction logs and flag abnormal observations to the supervising chemist

What we are looking for

- B.Sc. or M.Sc. in Chemistry, Materials Science, or Polymer Science.
- Basic understanding of lab reactions and analytical testing
- Comfort with standard lab equipment and safety procedures
- Accurate record-keeping and SOP discipline
- Prior experience in resin, coating, biomass, or chemical processing labs is a plus, but not required

What you get

- Hands-on experience with bio-based chemistry
- Direct mentorship from a senior scientist
- Visible contribution in a small team working at production scale
- A clear path to a full-time role based on performance
