reducing wastes in the healthcare processes is crucial for developing a high performance health system. adopted from the toyota production system (tps), the lean concept has emerged in recent years as a way of introducing innovative ideas to improve industrial processes. in the context of health care, lean is considered as a continuous improvement model, which provides healthcare organization t...

This article presents the use of the Simulated Annealing algorithm with a heuristic to solve the waste minimization problem in roll cutting programming, in this case, paper. Client orders, which vary in weight, width, and external and internal diameter, are fully satisfied. Several tests were performed with real data from a paper company in which an average of 30% waste reduction and 100% reduc...

Anaerobic digestion is an engineered methanogenic decomposition of organic matter under oxygen-free conditions and involves a mixed consortium of different species of anaerobic microoganisms that transform organic matter into biogas. The process is successfully used for the treatment of municipal sludge, animal manure, industrial sludge, and industrial and municipal wastewaters. Applications of...

The current study aims to analyze waste characteristics and management practices of the hotel industry in Hoi An, a tourism city in the center of Vietnam. Solid wastes from 120 hotels were sampled, the face-to-face interviews were conducted, and statistical methods were carried out to analyze the data. The results showed that the mean of waste generation rate of the hotels was 2.28 kg/guest/day...

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...

Presently waste incineration is one of the most commonly used techniques for residual waste processing. It is an important step of making inert and compacting the waste before disposal. More strict legal regulations for the reduction of emissions requires the improvement of existing process control. This chapter presents several methods and approaches to improve the current status of process co...

Determining the seasonal and annual quantities and compositions of the municipal solid waste and assessing the present management conditions of three urban communities in the northwest of Iran were the core objectives of this study. Our findings revealed that the average daily per capita of municipal waste generation was 0.489–0.841 kg/cap-day. Organic and food waste comprised the largest part ...
