    Downcycling PLASTIC from rivers

Downcycling - Better less value than no value at all

A study of 1,350 rivers showed that only 10 of them contribute the most plastic waste to the oceans.
These are mainly the Nile, the Niger and the eight major Asian rivers!
Not even 5% of all plastic waste produced worldwide is actually recycled. Where does the remaining 95% end up?

If an endlessly circling collection net loop is placed in front of the delta of these (and other) rivers, on both sides of the river banks, most of the floating debris can be shredded off with the current.
The two net loops, which extend slightly over the centre, are spaced apart so that they are easy to navigate around for boat passages.
The constantly circling endless net turns horizontally at the shore and shakes the caught material down onto a conveyor belt. The belt feeds the yield directly to a high-quality downcycling plant provided.
A model for such sensible recycling plants could possibly be

 The KIT pyrolysis reactor heats plastic waste in order to recover raw materials.

Two additional coarse nets are required upstream to fish out heavy coarse driftwood, which would tear the finer nets for the plastic waste particles.

However, microplastics also require us to avoid driving unnecessary kilometres by car. Likewise, plastic clothing and, of course, all plastic packaging has an outsized share in this.

Similarly configured, floating river turbines could be placed in parallel as large carpets and supply large amounts of electricity. Each of these paddlewheel rollers in combination would already provide valuable, cheaply generated operating power in the kilowatt range, 24 hours a day. See also: Electricity buoy from AquaLibre,

      UPCYCLING for Cargo Ships                            

Each of the tens of millions of cargo ships that cross our oceans is downcycled in third world countries after its seaworthy service life.

These constructively valuable superstructures could instead be given a second, useful life:

On moorings or pulled ashore with the keel upwards, they would - with an appropriately extended operating licence and converted into multi-purpose premises - continue to provide valuable services for many years to come. Whether as a school, opera house, museum, department stores', gallery, hospital, restaurant or for communal living, such a ship's belly offers many possibilities. In new builds, such facilities cost scarce resources anyway, take up a lot of urban space and hardly have any more living space.

These approaches should also be considered by UNHCR and UNIDO for further implementation.

Rough vacuum application in the interior of freezer and cold storage rooms

Suggestion for the manufacturing industry of refrigerators, refrigerated containers, refrigerated lorries, refrigerated wagons etc..

Designed as an airtight cooling housing, a low vacuum is generated by a vacuum pump when the door is closed in order to keep the stored food fresh for several times longer (Tupperware® effect).

When the door closing mechanism is actuated, the air sucked out can immediately flow back in again (pressure equalisation). The door handle recessed in an olive first opens the air inlet valve. Only after this immediate pressure equalisation can the door be opened without resistance.

Each time the door is closed, a sensor or switch causes the air to be pumped out again; however, the sensor can also be deactivated.
The condensation drain allows the liquid to drain away each time the cold room is opened (via a vacuum ball valve). When the door is closed or the air is evacuated again, the valve closes this drain again.

Of course, there are already a large number of different rain boots on the market. From work to fashion, there are models for every need, but there is also a need for work in boggy deep mud, which is particularly energy-sapping.

To ensure normal walking in viscous wet mud, an open, integrated 2 mm air channel, which runs down the calf shaft in the boot and then through the heel sole to the instep arch, is all that is needed.

This means that the foot does not have to form a strenuous suction stamp with the boot, and you can walk almost unhindered as if on neutral ground.

It is irrelevant that this channel absorbs some of the mud with every step, as this amount is easily released again pneumatically.

Inflatable wings for cargo ships too

90 % of all long-distance freight is transported by "dirty" sea routes.

This should and must change in the future. Now it can be realised easily and cheaply! With the simple and revolutionary invention of two Swiss inventors, even 1000 m² sail areas can be realised. Large ships can even be equipped with several thousand square metres of wind power.

See the 8 min. VIDEO: 

IWS consist of a double skin as a symmetrical flow profile. Fans in the leading edge stabilize the sail shape for all wind conditions and a free-standing, retractable mast is at the aerodynamic center of the wing.
The advantages of IWS: The sail flies vertically. The NACA profile was created to develop high driving force for a low righting moment. The symmetrical airfoil is balanced and in the best position to maximize driving force. The aerodynamic center remains stable in all wind conditions. This type of sail can be operated in system automation.
IWS reduces effort on the boat: Shape control via internal pressure, no slats, no local stress. The wing flies vertically and does not create local tensions in the membrane, lightweight canvas.
Little heel angle against the wind. Perfect for gigantic sails such as superyachts, oil tankers etc. Freestanding, retractable and lightweight mast hidden in the wing.
IWS behaves like a muscle, STABILIZED BY HIGH PRESSURE. No compressive forces in the rigging, allowing the use of a retractable mast. Deflating the IWS is done by deflating the wing and retracting the mast. The lightweight boom, is integrated into the wing and accommodates the part of the sail that has been dropped and deflated. These approaches should also be considered by UNIDO for further implementation.


2050 - more plastic than fish in the sea!

8 million tons of plastic waste end up in the world's oceans every year. Visually: a truckload of plastic is dumped into the water every minute!

It is now up to our economically leading nations to implement technical implementations here...
