WO/2015/119517 ENVIRONMENTALLY-FRIENDLY WATERLESS TOILET||WO||13.08.2015|
||PCT/PA2014/000002||IES-INGENIERIA ELECTRICA ESPECIALIZADA|
The invention relates to an environmentally-friendly waterless toilet that uses biodegradable packs. The invention is provided with a device for packing human faeces using a system for bagging, sealing and packing same in biodegradable plastic bags, to be transported to suitable locations for storage and subsequent treatment. For this purpose, the invention comprises rollers with toothed wheels at the ends thereof, the surface being provided with a notch and a wedge for sealing and cutting. The invention also includes an endless screw for pushing the bags into another larger bag. The system saves all the water normally used as a transport means in the treatment of human faeces and urine.
WO/2015/093991 CONTINUOUS INDUSTRIAL METHOD FOR THE PRODUCTION OF BIODIESEL FUEL||WO||25.06.2015|
||PCT/PA2013/000003||ALS BIOENERGY CORP||SCAPARRO, Ariel, Leonardo|
Continuous industrial method for the production of biodiesel fuel comprising a step of interesterification of triglycerides with a methyl or ethyl ester having up to 6 carbon atoms in an ultrasonic cavitation reactor and in two stirred tank reactors, the product being filtered to recover the reaction catalyst; a step of recovering the unreacted methyl or ethyl ester by means of two vertical evaporators and flash evaporation; and a step of separating and obtaining the biodiesel by distillation of the solution obtained from the flash evaporation using short path distillation in distillation columns arranged in series.
WO/2014/200368 DEVICE AND TECHNIQUE FOR THE BIOLOGICAL DIGESTION OF WASTE EFFLUENTS BY FLUIDISED BEDS AND LIMICOLOUS FILTRATION||WO||18.12.2014|
||PCT/PA2014/000001||INISA AMBIENTAL, S.A.||LAUCEVICIUS, Carlos|
The invention relates to a device and a technique for the digestion of effluents by fluidised beds and limicolous filtration, said device consisting of four independent, intercommunicating tanks, without sludge recirculation, for treating liquid effluents in a vertical biological manner, with biological stratification by means of air injection pressure control, and filtration devices comprising elements which favour the adhesion of lime. The waste effluents follow a continuous and ordered flow throughout the process, resulting in water which satisfies the regulations for the discharge of effluents to receiving bodies of water and sewers.
