With urbanization, population, and consumption on the rise, urban waste generation is steadily increasing. Consequently, management systems have become integral to city life, playing a critical role in resource efficiency environmental protection. Inadequate can adversely affect environment, human health, economy. Accurate rapid automatic classification poses significant challenge recycling. De...

Separating household waste into categories such as organic and recyclable is a critical part of management systems to make sure that valuable materials are recycled utilised. This beneficial human health the environment because less risky treatments used at landfill and/or incineration, ultimately leading improved circular economy. Conventional separation relies heavily on manual objects by hum...

To the Editor—Medical and healthcare institutions can be the source of life-saving medical interventions, but they also play a significant role as a vital energy hogs. At the same time, healthcare and medical institutions conduct different kinds of therapeutic activities that result in the production of infectious waste, sharp objects, radioactive waste, and chemical materials. Research conduct...

The management of municipal solid waste (MSW) in China is facing urgent problems with rapid industrialization and urbanization. This article focused on the status of Hangzhou, capital city of Zhejiang province, China. The regulations, policies, implementation, barriers and solutions about source separation, separate collection, clean & direct transportation, treatment and disposal were introduc...

In this work, a combination between Multivariate Statistical Process Control (MSPC) and an automatic classification algorithm is developed to application in Waste Water Treatment Plant. Multiway Principal Component Analysis is used as MSPC method. The goal is to create a model that describes the batch direction and helps to fix the limits used to determine abnormal situations. Then, an automati...

The classification performance, based on measurements obtained by a dedicated remote near-infrared sensor, is validated. Goal is the separation of demolition waste in three fractions: wood, plastic, and stone. In phase one, reference objects are collected and measured in order to develop the classification algorithm and to obtain reference classification results. In phases two and three, the va...
