A system including biogas purification and provides biogas as feedstock to a solid oxide fuel cell. The biogas purification treatment process provides a polished biogas that is substantially free of carbonyl sulfides and hydrogen sulfide. The system uses a biogas treatment apparatus, that includes apparatus such as a packed columns, comprising copper oxide or potassium permanganate packing material, and an activated carbon component configured to treat the biogas by polishing it to remove carbonyl sulfides and deleterious trace residues, such as hydrogen sulfide, that were not removed by any prior bulk H2S removal steps. In addition, an oil removal device is used to remove any entrained fine oil droplets in the biogas. A polished biogas having in the range of 60% methane is charged to the fuel cell. Electricity generated may be fed into a grid or used directly as energy to charge electrical-powered vehicles, for example. Energy credits are tracked in real time and are appropriately assigned.

The manufacturing method of high-efficiency plant composite type bacteriostatic deodorant based on HQ22 bean extract includes pretreating the leaves of certain beans and certain plants in the early stage, which are then respectively processed into powder by a pulverizer; uniformly mixing the two powders according to a certain mass ratio, which are then treated with inoculation process with a certain inoculation amount of Bacillus natto seed solution; carrying out fermentation treatment on that mixture to obtain dark brown fermentation liquor; separating and purifying the fermentation liquor to obtain active components of the high-efficiency bacteriostatic deodorant; mixing the active ingredient with a certain proportion of surfactant, buffer, solvent and flavoring agent; and then obtaining high-efficiency plant composite type bacteriostatic deodorant based on HQ22 bean extract was prepared. The method has the advantage of high-efficiency of deodorization and bacteriostasis.

A method may be provided for inactivating biologically active components in a liquid using low-energy electrons generated by an electron source, the electrons having an acceleration voltage of 25 keV to 300 keV. The method comprises the following steps: a) filling a vessel with a liquid volume; b) applying low-energy electrons to a first partial volume of the liquid filled into the vessel, wherein the first partial volume is a maximum of 10% of the liquid volume in the vessel; c) mixing the first partial volume of the liquid, applied with the low-energy electrons, to the second partial liquid volume in the vessel, which has not been applied with low-energy electrons; d) repeating steps b) and c) several times.

The invention concerns a process for making compounds using wastes of natural origin and fibres of plant or animal origin, wherein wastes of natural origin, fibres of plant origin, as well as wastes of animal origin, composing the so-called “charge”, are mixed with agglomerating plastic materials, the so-called “carriers”, and with agglomerating additives in order to form a mixture, the so-called “blend”, which is transformed into a compound, the “compound”, used for making semi-finished products. Said process occurs five sequenced steps that goes from the preparation of the “charge” and the “blend” to the selection of the “carriers” and agglomerating additives till the process of the “blend” to obtain the “compound” and finally to the process of the “compound” to obtain a semi-finished product. According to the invention the initial “charge” is submitted to a sanitization treatment, based on the principle of advanced oxidation, obtained by applying the technological process referred to as “Non-thermal plasma” or

“NTP”, where the so-called “non-thermal discharges with dielectric-barrier method” or “DBDs” are used, in order to strongly reduce bacterial charges, until removal thereof, decompose the volatile organic substances (VOCs) and remove smells.

The present invention relate to a waste mask treatment device using a sterilizing material, and more particularly, to a waste mask treatment device including: a body with an inlet adapted to insert a waste mask thereinto; a pulverization part located inside the body to pulverize the waste mask into pieces of mask; a sterilization part for emitting a sterilizing material for sterilizing the pieces of mask; and a collection part for collecting the pieces of mask. Accordingly, the waste mask treatment device is capable of being conveniently movable, being compact in size, and eliminating more than 99.99% of harmful bacteria living on the disposable mask through the sterilizing material.
