BD Gone Bad? Recycle That Biodiesel Waste

OK, we've taken you step-by-step through the biodiesel making process ... we've shown how to do a titration test and a mini batch test on waste vegetable oil ... we've shared the tricks for determining a recipe of ingredients for foolproof BD, and we've even offered up tips on how to collect waste oil from restaurants.

Then y'all started asking questions about how to troubleshoot biodiesel reactions when things go wrong, and worse yet, "what do I do if it all goes bad and I can't fix it?" This is the give and take of the online world--you post a query, we post and answer. So now, when it all goes belly-up, you'll know how to dispose of biodiesel waste.

Any other burning BD questions on your mind?
