Thermal hydrolysis technology (THT) is an advanced waste treatment process that is increasingly being adopted onboard marine vessels to manage organic waste and sludge effectively. This technology enhances biodegradability and facilitates subsequent treatment processes, ensuring compliance with international marine pollution regulations such as MARPOL Annex IV and V. THT is …
Vacuum-based waste collection systems are used onboard ships to efficiently manage and transport sewage and other wastewater to treatment facilities. It is recognized as a highly efficient and environmentally friendly solution for managing different types of residues onboard ships. By using vacuum pressure to transport waste, this system offers significant …
Exhaust Gas Cleaning Systems (EGCS), commonly known as scrubbers, are designed to reduce the emissions of sulfur oxides (SOx) and particulate matter from ship exhaust gases. These systems are critical for ensuring compliance with international maritime regulations, such as the IMO 2020 sulfur cap, which limits the sulfur content in …
MEPC 80, held in July 2023, discussed amendments to MARPOL Annex V regarding the discharge of garbage from ships. One of the key topics was the consideration of new technologies for onboard waste treatment, including devices that use mechanical friction to convert waste into a sterile, dehydrated biomass. The mechanical …
Ballast water is essential for maintaining the stability and structural integrity of ships during voyages. However, the discharge of untreated ballast water poses significant environmental risks by introducing invasive aquatic species to new ecosystems. To mitigate these risks, international regulations, such as the IMO Ballast Water Management Convention, mandate the …
