An entirely water-based, energy self-sufficient, integrated in-line waste management system is provided for comprehensive conversion of all organic fractions of municipal and wider community waste to fuels suitable for use in transportation, with all solid residues converted to high nutrition compost. The system is based on a combination of pre-treatment, involving alkaline hydrolysis and saponification; three-way separation of the pre-treated waste into different streams that are each directed to suitable further processing including fuel production; which includes biodiesel generation in a continuous-flow catalytic esterification unit, and anaerobic digestion to produce methane or other small molecule biofuel. Remaining solids are converted to compost in a quasi-continuous process.

The disclosure relates to the field of solid biofuels obtained by steam cracking. More particularly, the disclosure relates to a process for the treatment of lignocellulosic biomass by steam cracking in which the obtained powder is treated in order to separate the particles into two categories according to a threshold value, and each category is treated differently.

A method for producing a biofuel by continuous or discontinuous steam cracking of lignocellulosic biomass includes: —recording a digital model of the optimal steam cracking parameters as a function of the nature and the content of the contaminants; —introducing a biomass containing at least part of the contaminated biomass into the steam cracking reactor; —measuring at least once during the treatment the nature and content of the contaminants; and —controlling the adjustment of the steam cracking parameters as a function of the nature and the content of the measured contaminants and of the digital model.

A method for producing a biofuel by continuous or discontinuous steam cracking of lignocellulosic biomass, comprises: —recording a digital model of the optimal steam cracking parameters as a function of the typology of the plant constituents of the biomass; —supplying the steam cracking reactor with heterogeneous biomass; —measuring at least once during the treatment the typology of the plant constituents of the biomass; and —controlling the adjustment of the steam cracking parameters as a function of the typology of the plant constituents of the measured biomass and of the digital model.

The purpose of the invention is to reduce various costs including a device manufacturing cost, an energy cost and a running cost by omitting a drying step of a product produced by hydrolyzing a waste with steam, a pellet molding step, and a treatment step for exhaust gas generated by combustion of pellets. A waste biogasification treatment device for subjecting a raw material containing organic waste to hydrolysis treatment and biogasification comprises a hydrolysis device and a biogasification and recovering device for biogasifying the product produced by hydrolysis treatment and recovering generated biogas. The hydrolysis device comprises a treatment vessel having a raw material charging port and a product discharging port; a stirring means provided inside the treatment vessel and stirring the raw material; a steam supply pipe for supplying steam to the treatment vessel; and a steam exhaust pipe for discharging steam from the treatment vessel.

A method of at least partially breaking down a material or product item or combination of material or product items. The method includes the steps of introducing said material or product item or combination of material or product items into a treatment vessel, introducing at least one working fluid into the treatment vessel, repeatedly increasing pressure on the material or product item or combination of material or product items in said treatment vessel to above atmospheric pressure and then subsequently depressurising the material or product item or combination of material or product items in the treatment vessel to achieve a pressure reduction in the vessel to effect at least partial breakdown of said material or product item or combination of material or product items.
