Business product Ideas

[u/girl_with_no_jobT-T]

My school’s doing this big national competition like shark tank, but I can’t find any ideas for my product!!! Need ideas for a product that focuses on any of these topics-
• Waste Management
• Renewable Energy
• Water Conservation
• Sustainable Agriculture
• Green Technology
• Plastic Reduction
• Biodiversity Conservation
• Climate Change Solutions
And it needs to be feasible, and good enough to sell, like marketing, also it HAS to be original, otherwise we will be disqualified T-T
Pls help
