High-density polyethylene (HDPE) is a widely used and recyclable plastic. Nonetheless, the presence of polypropylene (PP) contamination poses a significant issue in recycled HDPE streams.

Plastic Mixture

 

Can PP and HDPE be recycled together?
PP and HDPE are distinct types of plastic with different chemical compositions and properties. When they are mixed together in the recycling stream, it can result in various issues:

Reduced quality: Mixing PP with HDPE can lead to lower-quality recycled HDPE material. The properties of the resulting plastic may not meet the required standards for certain applications.

Compatibility issues: PP and HDPE have different melting points and processing requirements. Combining them can make it difficult to maintain the consistency and quality of the recycled material during the melting and molding stages.

Material weakness: The combination of PP and HDPE can result in a recycled material that has reduced strength, durability, and performance. This can be problematic, especially in applications where HDPE's mechanical properties are critical.

Identification and Separation of polymers in the industry
One of the biggest challenges facing the plastics recycling industry today is separating all of the various polymers entering the recycling stream. Separating PP from HDPE during the recycling process can be challenging due to their similar appearance. This can result in contamination if they are not adequately separated at recycling facilities.

To mitigate contamination issues, recycling facilities often employ advanced sorting and separation technologies to ensure that PP and HDPE are properly separated. This involves using optical sorters, air classifiers, and other equipment to identify and separate different types of plastics.

Near Infrared (NIR) Sorting Technology

Among them, the NIR-based sorting machines are widely used in the recycling industry to identify and separate various types of plastics based on their unique spectral signatures in the near-infrared range. These machines can accurately differentiate between different polymer types, such as PET, HDPE, PP, PVC, and more, facilitating the efficient recycling of plastics and reducing contamination in the recycling stream.

Water supply on the boat -

To supply water on the boat, a number of water pumps are used and named according to their purpose and application.

Pressure water pumps

Fresh water pumps, pressurised water pumps & drinking water pumps supply fresh water on board. They are used to deliver the water from the tank to an outlet. Pressurised water pumps are located in the boat outside the water tanks. When they are switched on, water pressure in the pipes on board remains constant, so that the water reaches the outlet at full capacity. 

In line pumps

In-line pumps are ideal for the drinking water systems on smaller vessels. One in-line pump is used to supply water for each fresh water tap. In-line pumps can be installed like valves in pipelines and are connected to the outlet with a hose and cable. In-line pumps are operated via microswitches on the water tap (tapping point). In-line pumps for small boats are characterised by their low power consumption. 

Flushing pumps

Flushing pumps are used for toilets, for example. They draw in seawater for flushing and only activate when the toilet flush switch is pressed.

Shower water pumps

If used water, e.g. from the washroom, needs to be transferred to grey water tanks, it is best to buy a shower water bilge pump. Shower water bilge pumps in 12 V or 24 V from RM can be found in our range of fresh water pumps. 

Double-port pump

Double-port pumps can be used, for example, to fill a tank (fish tank, ballast tank or similar) with seawater and at the same time wash the deck.

Water pressure systems / pressurised water systems

These systems are complete, compact pump systems featuring a pressure compensation tank, filter and other components. The compact systems are particularly suitable for boats with high water requirements. 

These water pressure systems require various components to function correctly for them to be effective. Pressure compensation tanks, filters and other accessories can be found in our Website.
