Challenge details:
Painting processes generate paint sludge, a hazardous waste consisting of overspray paint particles and other residues. A typical paint shop generates approximately 140 MT of paint sludge annually. Disposing of this waste is a persistent challenge due to its adverse environmental impact. Increasingly stringent regulations necessitate exploring alternative, green recycling solutions.
Efforts to recycle paint sludge into fresh paint have failed to meet essential quality-specific parameters, including viscosity, color consistency, dry-film thickness, gloss and drying time etc.
We, therefore, seek innovative, sustainable and easy-to-implement solutions for recycling of paint sludge that offer environmental benefits without incurring additional costs. Your contributions can help mitigate environmental risks, comply with stringent regulations, and create value from waste.
Sustainable packaging material for internal logistics of jewellery articles
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
We are seeking innovative, cost effective solutions that can prevent in-transit damages tojewellery articles by restricting their motion within the packaging. The packaging solution must be made of sustainable materials and be reusable if possible with low cost. Due to large variety of jewellery designs, it is desired that any packaging solution must be suitable for a broad range of shapes and sizes of jewellery to minimize the total number of SKUs.
Sustainable Packaging Solution for Edible Salt Transport
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
We are looking for an innovative, sustainable, and food‑safe packaging solution to replace the current 50‑kg bags used for edible salt.
Digital Traceability for Individual Solar Cells Across the Manufacturing Lifecycle
Rewards proportional to the value add! Few solutions could be available! Efforts might be needed to customize the solution.
We are looking for a non‑invasive, robust solution to uniquely identify each solar cell throughout manufacturing and maintain its identity from full cell to final module.
Automated removal of crown wheel from furnace for quenching
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
Crown wheels, which are critical components in automotive axles, are heated in a furnace to temperatures exceeding 960-degree C. The crown wheels are stacked together - typically 5 or 6 crown wheels - and each crown wheel is separated by a spacer (fixture). There are 25 types of crown wheels across 5 distinct families, each requiring precise thermal treatment.The crown wheels can weigh up to 45 Kg and have a diameter of 200-400 mm.The crown wheels need to be picked from the furnace and placed on the quenching fixture, before which the spacer needs to be removed. The takt time for one crown wheel is 1 minute.
Zero waste discharge solution for chemical sludge and ATFD salts from electronics manufacturing
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
We are seeking practical, scalable, and economically viable solutions that can eliminate/reduce the sludge waste and ATFD salt volumes generated through the ETP and ZLD facilities and identify potential value creation through resource recovery pathways. The treatment process should be capable of seamless integration with the current operations.
Separation of Zn and Fe from GCP sludge cake
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
We seek technologies capable of recovering zinc from blast furnace gas cleaning plant sludge so that it can be safely and effectively reintroduced into the pellet‑making process. Any solution must be compatible with the sludge's typical composition—more than 20% carbon, 6-10% iron, and measurable quantities of manganese, calcium, and other heavy metals—while reducing its hazardous characteristics. Technology providers are expected to deliver end‑to‑end solutions, including feed preparation, zinc recovery processes, and downstream offtake arrangements. Proposed approaches should ensure long‑term operational feasibility and support the company's broader circular‑materials strategy.
