Sea Cleaning, Lake cleaning, River Cleaning, Marine Debris



Marine debris, also known as marine litter, is human-created waste that has deliberately or accidentally been released in a lake, sea, ocean or waterway. Floating marine debris tends to accumulate at the center of gyres and on coastlines, frequently washing aground, when it is known as beach litter or tidewrack. Deliberate disposal of wastes at sea is called ocean dumping. Naturally occurring debris, such as driftwood, are also present.

With the increasing use of plastic, human influence has become an issue as many types of plastics do not biodegrade. Waterborne plastic poses a serious threat to fish, seabirds, marine reptiles, and marine mammals, as well as to boats and coasts. Dumping, container spillages, litter washed into storm drains, and waterways and wind-blown landfill waste all contribute to this problem.

Aspects of Marine Pollution estimated that up to 80% of the pollution was land-based. A wide variety of anthropogenic artifacts can become marine debris; plastic bags, balloons, buoys, rope, medical waste, glass bottles and plastic bottles, cigarette lighters, beverage cans, polystyrene, lost fishing line and nets, and various wastes from cruise ships and oil rigs are among the items commonly found to have washed ashore. Six pack rings, in particular, are considered emblematic of the problem.

Ghost nets

Fishing nets left or lost in the ocean by fishermen – ghost nets – can entangle fish, dolphins, sea turtles, sharks, dugongs, crocodiles, seabirds, crabs and other creatures. These nets restrict movement, causing starvation, laceration and infection, and, in animals that breathe air, suffocation.


8.8 million metric tons of plastic waste is dumped in the world’s oceans each year. Asia was the leading source of mismanaged plastic waste.

Debris removal

Techniques for collecting and removing marine (or riverine) debris include the use of Sea Cleaning Vessel. Devices such as these can be used where floating debris presents a danger to navigation.

Once debris becomes “beach litter,” collection by hand and specialized beach-cleaning machines are used to gather the trash.

Elsewhere, “trash traps” are installed on small rivers to capture waterborne debris before it reaches the sea.

We operate and hire sea cleaning boats for municipalities to collect debris on the surface of the sea or lakes or rivers.

Algae & Algal Blooms removal

Algae is an informal term for a large, diverse group of eukaryotic organisms that are not necessarily closely related and are thus polyphyletic. Included organisms range from unicellular genera, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga that may grow up to 50 meters in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem, that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae that includes, for example, Spirogyra and the stoneworts.

Since ‘algae’ is a broad term including organisms of widely varying sizes, growth rates, and nutrient requirements, there is no officially recognized threshold level as to what is defined as a bloom. For some species, algae can be considered to be blooming at concentrations reaching millions of cells per milliliter, while others form blooms of tens of thousands of cells per liter. The photosynthetic pigments in the algal cells determine the color of the algal bloom and are thus often a greenish color, but they can also be a wide variety of other colors such as yellow, brown or red, depending on the species of algae and the type of pigments contained therein.

We design and hire our Sea Cleaning Vessels for municipalities to collect and recovery for marine debris, algae, algae blooming either coastal seas, freshwater lakes, rivers or beaches.
