NOVELTY - Thermal treatment system (100) comprises: a solar concentrator (108) having an area of concentrated solar power (106); at least one fiber optic cable (104) having a first end proximate the area of concentrated solar power and a second end; and a solar reactor (102) coupled to the second end of the fiber optic cables, where the reactor comprises a container to receive material to be treated and insulating material surrounding the container.    USE - The system is useful for treating biomass and animal waste (all claimed) to produce char that is used in soil applications for agriculture.    ADVANTAGE - The system: converts animal waste or other biomass to biochar in cost effective manner without intensive pre-drying; and provides biochar that improves soil fertility, sequesters carbon, controls transport of environmental contaminants and removes pesticide, and gases that are utilized as cooking and heating fuel, or supplementing fuel for biochar production.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) treating (M1) biomass, comprising: providing a solar collector to obtain concentrated solar thermal energy; providing a reactor; providing biomass to the reactor; providing concentrated solar thermal energy to the reactor using the fiber optic cables; and treating the biomass with the concentrated solar thermal energy; and    (2) treating (M2) animal waste comprising: providing a waste treatment system comprising a solar collector and the reactor, where the reactor receives concentrated solar energy from the solar collector; exposing solid waste to the concentrated solar energy in the reactor to produce char; and exposing liquid waste to at least one of concentrated and passive solar energy to treat the liquid waste.
