This invention discloses a method for the synthesis of furfural and ethanol from green coconut (Cocos nucifera L.) husk. The method involves chemical reaction for furfural production and a biological fermentation for ethanol synthesis. In the chemical step, the green coconut husk undergoes acid hydrolysis in a high-pressure reactor, yielding furfural. The residual waste from this step is then utilized as a substrate for fermentation by Saccharomyces cerevisiae, producing ethanol. The integrated approach efficiently converts the cellulosic and hemicellulosic components of the green coconut husk into two industrially valuable compounds, furfural and ethanol, from a single agricultural waste stream. The invention provides a cost-effective and environmentally sustainable method for resource utilization and waste reduction.

A method for incinerating organic matter derived from the treatment of wastewater, or of industrial or agricultural waste, such as sludge and notably treatment plant sludge, is in a fluidized-bed incineration furnace, the furnace including a chamber in the lower part of which there is a bed of particles, preferentially sand, constituting a fluidization zone, in which fluidization zone the organic matter is introduced as fuel whilst air is injected as oxidizer into the bed of sand from a wind box through a fluidization dome surmounting the box. The air passes through passages made in the fluidization dome, and the furnace is configured to treat a nominal value of volume of organic matter to be treated. The method includes a step of adjusting the volume of the fluidization zone as a function of the volume of organic matter to be treated in which, when the volume of organic matter to be treated is lower than the nominal value, the volume of the fluidization zone is reduced from an initial volume to a reduced volume, and the incoming air flow is reduced by closing air passages so only the passages opening into the thus reduced fluidization zone are left active.
