Abstract Over the years, organic solid waste has become main issue and is larger than plastic waste. According to local government data, reaches almost 50% of total This research aimed find out how effectively efficiently cylindrical rotating perforated drum types could handle generated from households. Also, analyze challenges, strengths, knowledge gaps, opportunities in implementing this tech...

Material handling is a loose loop in most assembly plants. Jiist-in-time (JIT) is a management philosophy that strives to eliminate sources of manufacturing waste by producing the right part in the right place at the right time. We propose to apply JIT principles to material handling in assembly plants. Material Kanbans are introduced as an effective means to control and balance the physical ma...

This study aimed to explore the perception healthcare sector teachers, students and graduates from two institutions of higher learning in Rio Grande do Sul, on the generation of waste from healthcare services. It used a qualitative research approach, performed with 13 teachers, 18 students and 12 healthcare professionals, who were collected through a focus group. The main results showed there i...

An assessment of the radiotoxicity of spent nuclear material and the fuel handling issues associated with plutonium (Pu) or transuranics (TRU) multi-recycling in PWRs using the CORAIL assembly concept has been performed. This necessitated the development of an analytical approach to solve directly for the equilibrium state of repeated recycle, including higher actinide content. The equilibrium ...

Printed Circuit Boards (PCBs) are an integral part of any electronic equipment. The growth of e-waste as endof-life electronic equipments at an exponential rate is producing large quantities of discarded PCBs. In India, current recycling and processing of PCBs is managed almost entirely by the informal sector or the unskilled labor (95%). The crude recycling activities cause irreversible health...

For a deep geological repository for spent nuclear fuel planned in Sweden, the safety assessment covers up to 1 million years. Climate scenarios range from high-end global warming for the coming 100 000 years, through deep permafrost, to large ice sheets during glacial conditions. In contrast, in an existing repository for short-lived waste the activity decays to low levels within a few tens of...

OBJECTIVES Informal reports have suggested that work as a waste collector entails exposures that cause gastrointestinal symptoms--such as nausea and diarrhoea. This study explores this hypothesis by correlating data on the type of waste collected, the persons' job function, the equipment used, and the times of the week and the year of reported nausea and diarrhoea. METHODS 1747 male waste col...
