The invention relates to a biofuel, particularly an advanced solid biofuel, comprising waste coffee grounds.

Helix shaped fire tinder, and fire tinder integration into a corkscrew to provide an easy secure carrying and readily available storage solution for the user. An apparatus for manufacturing a helix shaped fire tinder. A process including a means of making a fully waterproof helix shaped tinder.

Embodiments of the present disclosure describe binder materials from birch bark, methods of making the binder materials, fuel compositions comprising the binder materials, methods of forming the fuel compositions in the form of pellets and/or briquettes, and the like.

Embodiments of the present disclosure describe water-resistant and durably high energy-density binder materials from cutin-containing materials, methods of making the binder materials, fuel compositions comprising the binder materials, methods of forming the fuel compositions in the form of pellets and/or briquettes, and the like.

A system for forming a woody biomass component and a binder component into a solid fuel element having a predetermined density. The system includes a first compression assembly for compressing an uncompressed mixture of the woody biomass component and the binder component to provide a first compressed mixture formed into a preliminary element having a preliminary density. The system also includes a second compression assembly for compressing the preliminary element to form the solid fuel element having the predetermined density, which is greater than the preliminary density.

The insect repelling recycled fire log is a manufactured fuel product that is configured for use as a fuel in a recreational combustion activity such as a bonfire or a campfire. The insect repelling recycled fire log releases an insect repellent that encourages insects to move away from the immediate areas surrounding the recreational combustion activity area during the said activities. The natural insect repellent is an airborne repellent that is released by the combustion of the insect repelling recycled fire log. The insect repelling recycled fire log comprises a fuel, an accelerant, and an ignition apparatus.

A wax composition can be incorporated into a biomass mixture, such as a woody biomass mixture, for formation of pellets, such as wood fuel pellets. The addition of wax compositions with suitable amounts of n-paraffins relative to the amount of oil-in-wax can result in biomass pellets with improved properties, such as improved durability and/or reduced tendency to uptake moisture during storage. Addition of a suitable wax composition can also allow for formation of biomass pellets with improved properties while also reducing or minimizing the power requirements during pellet formation.

Spent potlining material contains spent potliner from aluminium electrolysis cells, and at least one hydrophobic binder. The hydrophobic binder being selected from wax, a waxlike compound or mixtures thereof. A method for producing a spent potlining material includes the steps of (a) providing spent potliner from aluminium electrolysis cells, (b) comminuting the spent potliner in at least one comminuting apparatus, (c) fractionating the spent potliner through a separating apparatus, (d) mixing the spent potliner with at least one hydrophobic binder, selected from wax, a waxlike compound or mixtures thereof, in a mixing apparatus, (e) portioning the mixture obtained in step (d), (f) withdrawing the spent potlining material The steps (b) to (d) are carried out in an inert gas atmosphere. Also, spent potlining material is used as fuel in power stations and also in connection with the production of mineral wool, cement and steel.

A fire-starting material is disclosed. The fire-starting material may include metal powder, fibers, oxidizers, other powdered fuels, and a binder. The binder may be a hydrocarbon or a combination of hydrocarbons made up of molecules with about 10 to about 80 carbon atoms. The binder may hold the metal powder and the fibers in suspension. Additionally, the binder (and hence the fire-starting material overall) may be manually pliable between about 5 and about 50 degrees Celsius. To use the fire-starting material, a user may manually deform the fire-starting material to tear off a piece thereof. The piece may be applied to a fuel source and lit on fire.
