a recent study. The process uses a digester system with microorganisms to break down organic waste into fertiliser. The resultant fertiliser was used in a low-energy greenhouse to produce a range of food crops. The method is a potential way to utilise food waste and reduce the energy consumption of food production as part of a circular economy. New system to convert food waste into fertiliser f...

Rising landfill costs have forced solid waste managers to consider waste streamreduction alternativessuch as household recycling. Explaining the factors which motivate households to recycle is important to regions where households must bear a large portion of the recycling cost because unit-based garbage disposal fees and curbside recycling are not feasible options. Empirical results indicate t...

The increasing awareness of environment protection had made the European Union request the enterprises, through legislation (such as WEEE, RoHS and EuP), to take the responsibility to minimize the environmental impact. Directive of WEEE stresses that producers are responsible for the collection and recycling of all electrical and electronic waste. This paper focuses on how manufacturers can mee...

In this paper, we present the ZenRobotics Recycler, a system that sorts construction and demolition (CND) waste by picking valuable objects from a conveyor belt using robotic hands. It is the first CND recycling system that reaches a useful purity of wood, stone, and metal without resorting to human sorters. We describe how we applied machine learning to solve some of the key problems such as r...

Pathology, microbiology, blood bank and other diagnostic laboratories generate sizable amount of biomedical waste (BMW). The audit of the BMW is required for planning proper strategies. The audit in our laboratory revealed 8 kgs anatomical waste, 600 kgs microbiology waste, 220 kgs waste sharps, 15 kgs soiled waste, 111 kgs solid waste, 480 litres liquid waste along with 33,000 litres per month...

Growth in construction activities increases the amount of construction waste generated. Recycling of construction waste is an important component of environmentally responsible construction, as it reduces the amount of waste directed to landfills. In addition, it enhances the resource recovery for future construction work. A model is presented in this paper to predict waste generation rates, as...

The identification and classification of plastics plays an important role in waste management and recycling processes. Present electrical and optical sorting techniques lack the required resolution for accurate identification in a high throughput manner for a diverse set of plastics commonly found in municipal waste. In this work a multi-spectral infrared spectroscopic technique is employed to ...

The ferroalloys industry has generated historically substantial solid waste. The accumulated waste causes serious problems to the environment. However, it is possible to transform the solid waste into an environment-friendly resource to serve the human being. Consequently, the construction of plants that are “environment-friendly” and that accommodate “recycling” has become a target of most fer...

This study presents the options for source-segregation and selective collection of recyclable waste fractions for Cetinje, Montenegro, with the aim of meeting the European Union 50% waste recycling target in 2023, and extending collection and disposal system that builds on the existing strengths of the city. To this end, three options were considered: (1) source separation and separate collecti...
