SOLAR POWERED MANTA: Plastic Garbage Collecting Ship

The world’s oceans are in trouble, and plastic pollution is one of the most pressing environmental challenges of our time. Plastic waste accumulates in our seas, harming marine life and ecosystems, and even ending up in the seafood that we eat. To combat this problem, a team of engineers has designed a solar-powered boat that cleans garbage from the ocean, called the MANTA.

The MANTA is an autonomous vessel that is powered by renewable energy, making it an environmentally friendly solution to a critical environmental issue. The boat uses a combination of solar panels, batteries, and electric motors to operate. It is designed to collect floating garbage, such as plastic bottles, bags, and other debris that litters our oceans. The MANTA can be deployed in areas with high levels of pollution, such as river deltas, coastal cities, and shipping lanes.

The MANTA was developed by the German engineering company, RanMarine Technology. The company’s founder, Richard Hardiman, was inspired to design the MANTA after witnessing the devastating effects of plastic pollution on marine life. Hardiman and his team recognized the need for an efficient and effective way to clean up our oceans, and the MANTA was born.

The MANTA’s design is based on the manta ray, a large fish that is known for its graceful movement through the water. The boat’s unique shape allows it to glide effortlessly through the water, collecting trash as it goes. The MANTA is equipped with sensors that allow it to detect and avoid obstacles, such as other boats or marine life. It is also designed to be able to operate in all weather conditions, ensuring that it can continue to collect garbage even in rough seas.

The MANTA’s solar panels are positioned on the top of the boat’s wings, which allows them to collect as much sunlight as possible. The panels are connected to batteries, which store the energy for use when the sun isn’t shining. The boat’s electric motors are highly efficient, allowing it to travel at speeds of up to five knots while using very little power.

The MANTA is controlled by an onshore team, who use a remote control to guide the boat through the water. The team can monitor the boat’s progress and receive data on the amount of garbage that has been collected. The collected trash is stored on the boat, and when it is full, the MANTA returns to shore to dispose of the garbage.

The MANTA has already been deployed in several locations around the world, including the ports of Rotterdam and Dubai. In Rotterdam, the MANTA collected over 1500 kilograms of garbage in just three weeks, demonstrating its effectiveness at cleaning up our oceans. The boat has also been used in the ports of Barcelona, Hamburg, and Singapore.

The MANTA’s impact goes beyond just cleaning up garbage. By using renewable energy, the boat is reducing its carbon footprint and helping to combat climate change. The MANTA’s autonomous operation also reduces the need for human intervention, making it a safer and more cost-effective solution than traditional garbage collection methods.


The amount of waste that the MANTA can collect depends on a variety of factors, such as the size of the boat, the amount of time it spends in the water, and the density of the garbage in the area it is deployed. According to the manufacturer, the MANTA has a daily capacity of collecting up to 2000 pounds (907 kg) of floating garbage, which is equivalent to about 2.5 cubic meters of waste.

During a trial period in Rotterdam, the MANTA was able to collect over 1500 kilograms of garbage in just three weeks. This demonstrates the boat’s effectiveness at cleaning up our oceans, particularly in high-density garbage areas such as ports and river deltas.

It’s important to note that the MANTA is just one tool in the fight against plastic pollution in our oceans, and it should be used in conjunction with other efforts to reduce waste and improve recycling. The boat is designed to complement traditional waste collection methods and can be particularly effective in areas that are difficult to access by other means.


The MANTA is just one example of the innovative solutions that are being developed to combat plastic pollution in our oceans. Governments, businesses, and individuals all have a role to play in reducing our reliance on plastic and ensuring that we protect our oceans for future generations.

The MANTA is an inspiring example of how technology can be used to address critical environmental challenges. The boat’s innovative design, autonomous operation, and use of renewable energy make it an effective and sustainable solution to the problem of plastic pollution in our oceans. As we continue to face the pressing issue of plastic waste in our oceans, it is important to support and promote initiatives like the MANTA, which offer a glimpse of a cleaner and more sustainable future.
