BOSTON -- It's a Boston-area business that lives by the mantra reduce, reuse and recycle. From heating the office to powering the vehicles in the field, a local business owner takes going green to all new heights.

NewsCenter 5's David Brown reported Tuesday that for more than 30 years, Boston Tree Preservation has been caring for mighty New England trees. They trim towering pines and care for majestic maples. The love of tree care, though, is rooted deep with Peter Wild -- the owner of the completely organic tree and landscape company.

"What happens is when people get into the green industry and they start to get their hands dirty and they start to touch plants, they develop a passion, and once you have that passion for the green industry there is no turning back," Wild said.

Wild said that the passion has been with him since the first gypsy moth landed. He's battled the woolly adelgid, and now the winter moth. He's done so all while remaining completely organic and completely green.

He has converted his fleet of 30 diesel trucks and cars to carbon neutral bio-fuel. In partnership with Whole Foods and local restaurants, he re-uses vegetable oil to fill the tanks.

The fertilizer that feeds customers lawns, shrubs and trees is recycled. A trough holds food scraps, organic waste, and 5 million worms.

"What they produce is called worm castings, and it's these worm castings that produce a highly-beneficial biological soil," Wild said.

Each week, the worms eat 60 pounds of food scraps. Their waste is sifted out and then brewed with kelp and molasses to produce a soil amendment and organic insect repellent.

Even the heat for the facility for the company is recycled and environmentally friendly. All of the scraps from the tree company are fed into a high-tech wood stove. It saves the company thousands of dollars every year and also reduces carbon emissions.

"There's fun in that process, and there are good conversations in that process, and when you feel good about what you are doing the people around you and your customers pick up on it," Wild said.
