LEED suggests that it is beneficial to compost materials. i have been chipping tree limbs and bushes that were moved or trimmed because of the build. i will also chip waste lumber for the build. below is a picture of my chipper next to some tree limbs that will soon be turned into chips. the chipper is powered by electricity. it is a patriot, a brand that seems to be very well built. it really is a pleasure to ponder its sturdiness. in 5 hours of continuous chipping, it did a wonderful job. i will occasionally give deserved praise to a brand or a service provider on the blog. i receive and shall receive no benefit from doing this. well maybe a thank you.
