Making 'green' cheese in Wisconsin

By converting cow manure into methane gas, the Crave Brothers have found a "greener" way to power their Wisconsin dairy farm

Our 'Making a Difference' report tonight is how Brothers are going green, a little bit at a time, by transforming an American tradition. Here is NBC’s Roger O’Neil down on the farm in Wisconsin.

Making fine Wisconsin cheese drives the economic engine of the Crave Brothers’ farm. But electricity turns the motor of their milk engines. With 6 thousand dollar a month utilities bills, the brothers forward decided to make their own power, from something Charles, the idea brother, knew they had an endless supplier--Manure.

I have been dreaming of this for 25 or 30 years, and I set an interest in trying to do things better than what has been done in the past. 5 years ago when the Crave Brothers decided to turn the dairy farm into a cheese factory, more than a few thought they have bitten off more than they could chew. But Brothers say it was a leap of faith then, like now, turning manure into electricity. What looks like a giant crock pot is now converting the cows’ waste into methane gas, which generates enough electricity to power the farm and an extra 120 of their neighbors’ homes.

George is the Brothers’ visionary. It takes a little bit of stretch, a little bit imagination. As we milk more cows, we will be able to power a lot more homes, and it will be good for everyone in our community.

And what’s left after the manure makes methane gas is a new odor-free potting soil and a new liquid fertilizer the Craves put on their fields.

Mark, the baby brother, says utilizing all of the farm waste just make sense. I don’t even look at myself as an active environmentalist. It is what I do. It all pulls together increased productivity, better conservation for the soil and the water.

Brothers responsible to each other, their community and the changing the future through innovation. One bowl of Mozzarella at a time.

通过将牛粪转化成沼气，Crave兄弟为自己的威斯康辛州乳制品农场找到了更加绿色环保的能量来源。

今晚我们的“Making a Difference”节目报道了Crave兄弟的事迹，他们一点一点地实现绿化和环保，在逐渐改变美国人的传统。我是NBC新闻的Roger O’Neil，现在来到位于威斯康辛州的农场。

制作优等奶酪的业务刺激了Crave兄弟农场的经济发展。但是电力成为他们制造牛奶的动力来源。他们每月的能量费用高达6，000美元，两兄弟决定自主开发能源，从一个叫查尔斯的人那里，兄弟们知道他们找到了终端能量供应者——粪便。

我梦想这一点已经有25或30年之久了，我希望能做得比以往更好。五年前，Crave兄弟决定将乳制品农场发展为乳酪工厂，却心有余而力不足。但是Crave兄弟说他们有一个坚定的信念，就是将粪便转化成电力。一个巨大的看上去没用的粪池现在将牛粪转化成了沼气，可以生产足够的电力公用农场和其他120多户邻居之用。

粪便转化成沼气之后剩余的是无味的肥沃的土壤和液态肥，Crave兄弟将这些施用在自己的田地上。

Mark是几兄弟中最小的一个，他说利用所有的农场废物也是行得通的。我不把自己看成一个积极的环境保护主义者，我所做的只是增加生产力，更好的保持水和土壤。

几兄弟肩负着对彼此，对社区的责任，同时还在通过创新改变未来，逐渐地。
