Key facts. E-waste is the fastest growing solid waste stream in the world (1).; In 2019, an estimated 53.6 million tonnes of e-waste were produced globally, but only 17.4% was documented as formally collected and recycled (2).; Lead is one of the common substances released into the environment if e-waste is recycled, stored or dumped …
Quick Key Facts. E-waste is the fastest-growing waste stream in the world; between 50 and 60 million tons are produced every year. The e-waste discarded in 2021 alone weighs more than the Great Wall of China: the heaviest man-made structure in the world.; 75-80% of e-waste is shipped to countries in Africa and Asia, where poor and …

Biconomy (BICO) is a multichain relayer protocol that seeks to enhance the user experience on decentralized applications (DApps).It strives to make web3 products as intuitive and user-friendly as web2 products. Biconomy focuses on transaction management and gas optimization, and aims to reduce gas costs. It achieves this by utilizing meta …
In this article, I'll use the example of scaling numerical data (numerical data: data consisting of numbers, as opposed to categories/strings; scaling: using basic arithmetic to change the range of the data; more details to follow) to demonstrate the importance of considering preprocessing as part of a greater structure, the machine learning (ML) pipeline.
Composting is the natural process of recycling organic matter, such as leaves and food scraps, into a valuable fertilizer that can enrich soil and plants.
As you can see, we have two different pipelines. One for the train dataset and one for the test dataset. See how we first apply the "map()" function and sequentially the "shuffle()". The map function will apply the "_preprocess_train" in every single datapoint. And once the preprocessing finished it will shuffle the dataset.
A classic mistake is to preprocess the training data and then forget about it. This can lead to very bad performance on unseen data. The training data and in-production data should always be processed in the exact same way. This is also valid if we import a model; we need to make sure that we use the preprocessor that led to the training data ...
Solid waste management is a universal issue that affects every single person in the world. As you can see in our new report, What a Waste 2.0: A Global Snapshot of Solid Waste Management to 2050, if we don't manage waste properly, it can harm our health, our environment, and even our prosperity. Poorly managed waste is …
In response to COVID-19, hospitals, healthcare facilities and individuals are producing more waste than usual, including masks, gloves, gowns and other protective equipment that could be infected with the virus. There is also a large increase in the amount of single use plastics being produced. When not managed soundly, infected medical waste could be …
U.S. State Universal Waste Programs Adopting the Federal Program. The universal waste regulations can vary from state to state in the United States. The majority of states have adopted the full federal universal waste program, however, others have only adopted some of the federal universal wastes.
WEPCO demonstrated that the conversion of waste to biogas is an innovative way to reduce waste and generate energy, thereby reducing demand.
Data Preprocessing the data before use is an important task in the virtual realm. It is a data mining technique that transforms raw data into understandable, useful and efficient format.
Preparing raw data for further analysis or machine learning techniques is known as data preprocessing.A crucial step in the analytical process, it enhances data quality, resolves discrepancies, and ensures that the data is correct, consistent, and reliable.It sets the stage for the effective analysis and decision-making by establishing a …
Power scarcity and pollution can be overcome with the use of green energy forms like ethanol, biogas, electricity, hydrogen, etc., especially energy produced from …
