Water & Waste Management

How Recycling Robots are Transforming the Waste Management Industry


The world is a gigantic landfill! Everyday tons of waste are generated from various households, hospitals, industries, construction and demolition sites and more. While today we have numerous ways to get rid of the accumulated waste, it still ends up affecting the safety and sustainability of the ecological system. Therefore, the best alternative is to reuse and recycle as much waste as possible. And offering an extra pair of hand in this are waste sorting and recycling robots.

Greyparrot seeks to resolve the waste crisis by using AI-based computer vision to provide actionable insights for the 530 billion-dollar global waste management industry.

The promise of the fourth industrial revolution

MIT Technology Review

The technology behind the First Industrial Revolution was water and steam power, which mechanized textile production. The innovation made factories commonplace, which brought more people to cities and caused social upheaval. In the second, electric power made mass production possible. The third was based on semiconductors, which facilitated the data processing that automated production and spawned the digital age. Now a fourth industrial revolution is taking shape. The technology behind it is the internet of things--networks of connected devices such as sensors, robots, and wearables.

Using Data to Help Turn Household Waste into Local Clean Energy


For my final capstone project in Flatiron School's Immersive Data Science Program, I decided to test my newfound skills and continue furthering my personal investigations into the relationships that exist between data, waste, and energy. Recently, I have been learning more about the various ways that Municipal Solid Waste (MSW) can be transformed into energy. The most promising and efficient technology that I have come across to date is Plasma Arc Gasification. In my research, I discovered that understanding specific composition details about the MSW to be used as feedstock is one of many critical steps in designing a plasma gasification facility. What I set out to do for my capstone project, was to see if I could find some MSW collection datasets and perform a Feedstock Analysis with the intent of calculating specific Waste Type Compositions, Energy Density (kWh/kg), and Total Energy (kWh) for each sample.

Edge computing and IoT sensors help cities plug a leak in water bills


A Texas company is using edge computing and IoT sensors to help cities modernize crumbling water infrastructure and inaccurate water meters. The American Society of Civil Engineers has given the country's drinking water system a D- for the last 10 years. Many components of city water systems date back to the Civil War era. Olea Edge Analytics is using 21st century technology to spot needed repairs and make sure water bills are accurate. Dave Mackie, Olea Edge Analytics' CEO, said the company combines edge computing with artificial intelligence and machine learning to help cities make more informed decisions.

Water quality and distribution monitoring software Ketos raises $18 million – TechCrunch


Water quality and logistics monitoring software Ketos has raised $15 million from a group of investors to take advantage of the growing demand for better water management tools and technologies. The potential for more stringent regulatory oversight of industrial water use and wastewater management from local, state and federal government coupled with increasing consumer and investor demands for better corporate environmental stewardship is driving an unprecedented adoption of technology and services aimed at increasing conservation and reducing waste across industries. Water monitoring can also provide relevant information to public officials about the potential for disease outbreaks and other health related issues in a population. Recently, monitoring wastewater streams have been used to detect outbreaks of the virus that causes COVID-19. The renewed attention on water is one reason why an investment arm of the banking giant Citi joined lead investor Motley Fool Ventures and Illuminated Funds Group to come as new investors into Ketos.

Applying Machine Learning To The E.Coli Class Imbalance Dataset


The E.Coli dataset is a very popular dataset to experiment on because it is a multi-classification that has several imbalances. The E.coli dataset is such a difficult dataset to find a solution for that I have not been able to find a lot written about it on the internet. Jason Brownlee, of suggested deleting the rows deleting the rows of the highly imbalance classes, but in my opinion such a practice defeats the purpose of endeavouring to make predictions. After much exhaustive research I was able to come up with a solution where all eight classes in the dataset were identified and predicted on. The E.coli dataset is credited to Kenta Nakai and was developed into its current form by Paul Horton and Kenta Nakai in their 1996 paper titled "A Probabilistic Classification System For Predicting The Cellular Localization Sites Of Proteins."

What is a Smart City? Definition from


A smart city is a municipality that uses information and communication technologies (ICT) to increase operational efficiency, share information with the public and improve both the quality of government services and citizen welfare. While the exact definition varies, the overarching mission of a smart city is to optimize city functions and drive economic growth while improving quality of life for its citizens using smart technology and data analysis. Value is given to the smart city based on what they choose to do with the technology, not just how much technology they may have. Several major characteristics are used to determine a city's smartness. A smart city's success depends on its ability to form a strong relationship between the government -- including its bureaucracy and regulations -- and the private sector.

Microsoft teamed up with a nonprofit using autonomous 'interceptor' boats to clean up the ocean and is helping it identify trash with machine learning


Cleaning up the oceans is a huge undertaking, especially for a single nonprofit based out of the Netherlands, but having Microsoft on your side is a nice bonus. Boyan Slat launched The Ocean Cleanup nonprofit in 2013, with the goal of cleaning up the Great Pacific Garbage Patch. Since then, the project has also embraced the goal of preventing new waste from entering the ocean by cleaning up rivers the carry many of the pollutants. In 2018, The Ocean Cleanup was a participant in Microsoft's annual hackathon, where volunteers work together on moonshots to try to come up with innovative solutions. The resulting machine learning models have helped The Ocean Cleanup track plastic and other waste, and informed how and where the nonprofit deploys its giant autonomous plastic collectors.
