Lagrange Point

Electronics power the modern world, but they come at a high environmental and energy cost. E-waste a serious problem as many of the elements in modern electronics cannot be easily recycled. Is there a way to produce electronics that are more environmentally friendly? Is it possible to make a circuit board or more simply even a transistor that doesn't rely on silicon? Can you imagine a Silicon Valley without actual silicon? Its possible to make recyclable electronics without silicon and instead relying only on carbon and cellulose. How can you get away from the use of chemicals or high heat in circuit fabrication?
