The stabilization of inorganic waste of various nature and origin, in glasses, has been a key strategy for environmental protection for the last decades. When properly formulated, glasses may retain many inorganic contaminants permanently, but it must be acknowledged that some criticism remains, mainly concerning costs and energy use. As a consequence, the sustainability of vitrification largel...

The environmental indicators and the classification of beach waste are essential tools to diagnose the current situation and to indicate ways to improve the quality of this environment. The purpose of this paper was to perform a quali-quantitative analysis of the beach waste on the Curva da Jurema Beach (Espírito Santo Brazil). Three transects were used with equidistant positioning over the tot...

This paper uses the 'lens' of integrated and sustainable waste management (ISWM) to analyse the new data set compiled on 20 cities in six continents for the UN-Habitat flagship publication Solid Waste Management in the World's Cities. The comparative analysis looks first at waste generation rates and waste composition data. A process flow diagram is prepared for each city, as a powerful tool fo...

This paper presents a significant method and a basic idea of waste heat recovery from high temperature slags based on Time Temperature Transformation (TTT) curves. Three samples with a fixed CaO/SiO2 ratio of 1.05 and different levels of Al2O3 were designed and isothermal experiments were performed using a Single Hot Thermocouple Technique (SHTT). The TTT curves established through SHTT experim...

The hypothesis of this research was that attitudes and behaviours towards the management of biodegradable municipal waste (BMW) are spatially variable among the commercial sector (non-household sector), even within a city of modest (1.2 million) population. For a select number of representative electoral districts in the Dublin, Ireland region, businesses were surveyed regarding attitudes and b...

Fruit and vegetables wastes not only have no commercial value, but also require expensive operations of removal and disposal, representing a significant cost for the manufacturers of plant products. However, this material may represent an important resource of commercially worth phyto-molecules endowed with various nutraceutical properties. In the present work, we have verified the possibility ...

In this-first every study for Chile, a neural network based hierarchical modelling approach is proposed for forecasting domestic waste generation for the whole country. Over 30 global variables from the 342 communes (municipalities) in the country were analysed extensively using statistical tools that led to 5 significant explanatory variables: population, percentage of urban population, years ...

production of lysine by corynebacterium glutamicum (ptcc 1532) from different agricultural by-products (molasses and pulpy waste date) was compared to glucose as raw materials. for this purpose, ammonium sulphate was selected as a constant nitrogen source. the effect of different nitrogen sources was also investigated with glucose as a constant carbon source. the production of l-lysine was exam...
