The recycling of these agricultural wastes may present clear
advantages from economical and technological point of view; the
reduction of costs related to use of alternative raw materials; the
reduction of consume of virgin raw materials; the obtainment of
porous bricks with insulating ability when woody biomass is used
and the obtainment of bricks with good mechanical properties
using biomass ash. Further, all the biomass are available everywhere
and are a renewable local resource
