Jacob commented on Compost Buddy

Great idea! Many places have CSA's (, and I assume they deliver to apartments(?). Since they are already dropping off food, I wonder if they could pick up compost from households at the same time and take it back to their farm to use. It would be efficient, and maybe they could offer a discount based on the amount of compost the household gives. Might be a convenient place to start!


Jacob commented on Chrono Foods

Really interesting idea! I was just at a grocery store this morning that had a section for foods nearing their expiry date, and people were flocking to it, so there could definitely be interest. But I'm wondering if it might be a herculean task to constantly rearrange the items in the entire store. Do you have any ideas to do so efficiently and cost effectively?

Love this idea too! So a couple questions: does the barcode of a product contain its expiration date? To your knowledge, do any grocery stores currently associate purchase history with your membership number, and then let you view it online? That would be amazing so the user doesn't need to manually enter any data.
