Making bioenergy from invasive hyacinth and prickly pear

Kenyans are innovating to find ways to reduce water hyacinth by finding practical uses for the invader. In 2018, a program was launched to turn the exotic species into biogas which is then offered to economically vulnerable households to use as a biofuel for cooking.
One proposal being considered: a scaled up industrial biogas plant that would use water hyacinth as a primary source of raw material. Efforts are also underway to convert another invasive plant, prickly pear into biogas used for cooking. A biocontrol insect is also proving effective, though slow, in dealing with prickly pear.
