How? By converting your weekly yard waste into biochar using your backyard BBQ. Once your yard waste has been reduced to its native carbon it can be bagged and disposed of ease with the trash, added to your compost heap or buried in that old family Cold War era bomb shelter.
Now that summer is here most of will be mowing the grass and firing up the BBQ. For those of us with a charcoal BBQ the leftover coals can be put to good use. I haven't tried with a gas grill yet, but I will. What we're going to do is make a simple biochar reactor and use the BBQ, some charcoal and a small fan to turn it into biochar.
Here's some helpful hints:
hint #1: Don't be an idiot. Make sure you produce more charcoal than you burn.
hint #2: Check your local burning regulations
hint #3: This stuff is hot, really hot, be careful
