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 quick 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
