Digging the wells creates the most significant waste, because it generates drilling muds, soil, and rocks. Recycling systems, non-polluting additives, and containment tanks are used to prevent ground contamination and reduce sludge production. All the other kinds of waste (from packaging material to rubber and wood) are generated in very small quantities and the vast majority can be recycled. Even the various components of the power plant can be salvaged and reused at the end of their installation lifecycle.
