Elevated Landscape Technologies (ELT) is a sustainable technology company. They provide green roof and living wall services. And they have nice people in their booth too.

Of course, there are a lot of green roof services out there. But what makes ELT interesting is that their roofs are pre-grown and modular - removing a lot of the barriers associated with conventional green roofing.

As far as their living walls are concerned, they are simple, easy to use, and not power-hungry. Again, they are modular panels that can be even arrive pre-grown.
