Battery waste in, clean biogas out: if you like the idea of turning used alkaline batteries into high‑performance pellets that clean up gas streams, this role will feel like a playground rather than a job. You will be the person who makes sure that what works in a beaker keeps working in a reactor, a pilot plant and finally in the real world of biogas plants.
About the role
Klinloop is developing a proprietary sorbent material, produced from specific alkaline battery residues through a hydrometallurgical route, to remove hydrogen sulfide from biogas. You will own the journey from lab recipe to robust, scalable production, working hand‑in‑hand with the CTO and a future COO in a small, science‑driven team.
Right now, the process runs at lab scale and a pilot plant is being set up. Your mission is to stabilise and scale that process, create solid operating and quality practices, and help transform a promising material into a reliable industrial product that customers can trust.
What you will do
- Lead day‑to‑day production of material batches,
from lab reactors to the pilot plant.
- Standardise the current hydrometallurgical process (leaching, precipitation, filtration) to reduce variability between batches and document clear operating procedures.
- Design and implement a quality control protocol, defining control points, tests and acceptance criteria to ensure batch‑to‑batch reproducibility.
- Drive the transition from powder to pellets: complete the pellet development work, optimise pellet properties (mechanical strength, structural stability, porosity) and verify that performance matches powder behaviour.
- Test and tune pellets so that they work reliably under real operating conditions, including biogas flow and pressure‑drop constraints.
- Manage operational basics: contact suppliers, request quotes and organise purchasing of raw materials, consumables and equipment.
- Carry out technology scouting and benchmarking versus alternative materials (for exam
