阿西布朗勃法瑞公司（ABB） pioneers cable protection solution from discarded ocean fishing nets
An estimated one million tonnes of abandoned, lost, and discarded fishing gear (ALDFG), the equivalent of 50,000 double-decker buses, litter the world’s oceans every year, endangering marine life as a major source of ocean plastic pollution.?To help address dangerous marine pollution, ABB Installation Products pioneered industry-leading cable protection crafted from 50% recycle-based polyamide using primarily recovered fishing nets.?
A sustainable alternative to conventional plastic-based systems used to protect critical power and data cables, ABB’s PMA EcoGuard PA6 RPPA conduit requires less energy and water to produce, reducing 30% of upstream Scope 3 greenhouse gas emissions and 50% of net freshwater use.
“ABB’s commitment to circularity and transparency extends across the entire product lifecycle from initial design and sourcing to manufacturing, through use and end of life. Developing advanced products from repurposed materials, like PMA EcoGuard cable protection, meets the demands of industrial applications, while helping provide jobs, protect marine life, preserve resources, and promote a more sustainable and environmentally responsible future,” said Andrea Castella , Europe Region Leader, ABB Installation Products Division.
WindWings latest: retrofitting cargo ships with rigid sails
Introducing large, rigid sails to cargo ship Pyxis Ocean has led to notable decreases in both fuel usage and carbon dioxide (CO2) emissions.
BAR Technologies, the designer of the WindWings, plans to enhance the technology by using three sails in future models, aiming to further increase fuel and emissions savings.
The retrofitted sails are made from the same material as wind turbine blades which can be folded while in port and then extended to stand at 37.5m in height at sea, allowing for significant operational flexibility and efficiency.
The trial of the UK-developed WindWings on the ship over a six-month period has demonstrated the potential for wind power to make a meaningful impact on the carbon footprint of the shipping industry.
During its voyage across the Indian and Pacific Oceans and the North and South Atlantic, the Pyxis Ocean reported an average daily fuel saving of three tonnes, which translates into a daily reduction of 11.2 tonnes of CO2 emissions when the sails were deployed. Projected over a year, it could mean the equivalent of removing 480 cars from the road, states shipping firm, Cargill, offering a glimpse into the environmental benefits of the technology. The promising results from the Pyxis Ocean’s trial with WindWings seems to offer immediate environmental benefits and allows the shipping industry to meet the challenge of reducing fossil fuel dependence fast.

A new Internet for the sea to protect oceans
Understanding how natural environments respond to human activity is critical for sustainability. For ocean environments, this requires monitoring sea life, a goal that requires a new generation of sensors that brings wearable technology underwater.
In a perspective paper published in Nature Biotechnology, an international team of scientists led by KAUST (King Abdullah University of Science and Technology) alumna Altynay Kaidarova, Ph.D and Ibn Sina Distinguished Professor Carlos M. Duarte examines the challenges and potential solutions in wearable technology for marine animals. Improvements in this technology, which is a major effort of KAUST’s Sensor Initiative, will provide valuable data for the conservation and restoration of marine communities and habitats while allowing blue economies to grow. They will also lead to a new concept introduced in the paper: the Internet of marine life.
Our well-being and economies are increasingly dependent on healthy oceans. For us to continue benefitting from the richness of the oceans, we must be able to track the health of marine life”, said Duarte. “For this reason, I led a project, funded under KAUST’s Sensor Initiative, to bring the wearable revolution to the ocean,” Duarte said about the importance of wearable technology in ocean research.
Bionic jellyfish explore the ocean
Researchers at Caltech , a science, engineering research, and education institute, are looking into the development of biohybrid robotic jellyfish by using their inherent capabilities of journeying fathoms below for the future of ocean exploration.
This endeavour, led by the Centennial Professor of Aeronautics and Mechanical Engineering, John Dabiri , aims to enhance these simple yet remarkably adaptable creatures with advanced electronics. The project will see them deployed as data-gathering agents across the vast, uncharted expanses of our oceans.
The importance of ocean exploration
Understanding the ocean is vital for comprehending Earth's climate system, and the oceans play a crucial role in regulating the global climate; yet our knowledge of its depths remains limited.
Covering around 70% of the earth's surface, the ocean is vital for life as we know it. However, more than 80% of this huge body of water still remains unexplored.
By harnessing the capabilities of jellyfish as autonomous explorers, the researchers aim to shed light on the oceanic conditions that influence climate patterns. This includes gathering data on temperature, salinity, and oxygen levels, which are crucial for predicting future climate scenarios.
