Claim 7:
8. A method of recycling organic waste into biogas and liquid fertilizer, implementing essentially anaerobic digestion processes, by a means of assemblable appliance, as an autonomic standalone unit, said method comprises:
(a) providing a compact kit-of-parts, configured for transportation in a folded form, said kit-of-parts comprising:
(I) a pliant material, characterized by a relatively high tensile strength;
(II) a pliable material characterized by a relatively low tensile strength;
wherein said relatively low tensile strength of said pliable material is lower than said relatively high tensile strength of said pliant material;
(III) a collapsible anaerobic digester disposed at a bottom portion of said assemblable appliance comprising:
(i) a structured shape;
(ii) at least one tensile element made of said pliant material having said relatively high tensile strength;
(iii) a sheeting element forming an essentially closed structure, made of said pliable material, having said relatively low tensile strength;
(iv) a plurality of apertures for connectors of said appliance comprising:
an inlet configured for feeding a semiliquid mixture of organic matter and water into said anaerobic digester;
at least one outlet, extending from a sidewall of said anaerobic digester;

(IV) a collapsible gas tank disposed at a top portion of said assemblable appliance comprising:
(i) a structured shape;
(ii) at least one tensile element made of said pliant material having said relatively high tensile strength;
(iii) a sheeting element forming an essentially closed structure, made of said pliable material, having said relatively low tensile strength;
(iv) at least one element selected from the group consisting of: a gas inlet and gas outlet;

(V) at least one pressure exerting mechanism, configured to facilitate increased pressure in said collapsible gas tank, selected from the group consisting of:
(i) elastic tension straps, comprising an elastomeric material, connectable to connectors elements attached to said appliance, and
(ii) a flexible elongated and foldable ballast bag, fillable with a ballast substance, said flexible elongated ballast bag is capable of assuming a conformation, respectively matching the shape of said collapsible gas tank;, wherein said assemblable appliance is characterized by lacking any rigid structural support scaffolding;
(b) assembling said lightweight structural appliance from said kit-of-parts;
(c) feeding a semiliquid mixture or slurry of ground organic matter and water into said collapsible anaerobic digester;
(d) sustaining essentially anaerobic digestion processes in said collapsible anaerobic digester;, wherein said assemblable appliance is characterized by lacking any rigid structural support scaffolding.
