The Malon have a vast interstellar civilization in the Delta Quadrant that produces over six billion isotons of industrial byproduct every day.
Malon Prime is a beautiful world; waste export is an important industry in order to keep the planet clean. Malon freighters travel thousands of light-years in order to dispose of their world's contaminated antimatter waste.
A Malon waste-export captain named Emck used a subspace vortex to dump contaminated antimatter waste into a void, whose indigenous population was being poisoned by the waste's theta radiation, until the U.S.S. Voyager destroyed the vortex.
