Co-exposure to mycotoxins: the case of waste management workers

Introduction - Occupational exposures are characterized by being complex and associated to co-exposure to several contaminants by different exposure routes. Even if exposure occurs to only a chemical agent, it can have different exposure routes and can result in different health effects. The waste management setting is recognized by the presence of several chemical and biologic agents in the workplaces. Recently, it was reported occupational exposure to Aflatoxin B1 (AFB1) in one Portuguese waste management industry. However, data regarding to fungal burden showed that exposure to other mycotoxins should be expected. Aim of the study - The aim of the present work was to know if workers from this waste management industry were exposed to other mycotoxins besides AFB1.

A waste management school approach towards sustainability

Education towards sustainability in Chemical Engineering (CEng) gave birth to awaste management program (WMP) at Instituto Superior de Engenharia do Porto, in Portugal. It involves students, teachers, and laboratory technicians. It aims to enhance the conscientiousness of the decision-maker next generation for saving resources, managing wastes, and at same time to develop applied chemistry understanding. This program was implemented in 1999 and is responsible for management and fate of all inorganic wastewater providing from training experimental activities of the CEng degree. An immediate reduction of wastes at their source was first defined. Wastes were collected separately and were reused, recycled or chemically treated, and after analytically controlled as legally imposed. Solids formed after this program were recycled, purified or followed suitable elimination. Global results point out environmental, pedagogical, and social benefits. Active participants are aware, in agreement, and publicly committed to the WMP.

Occupational co-exposure to several mycotoxins in the waste management setting

Contrary to fungi, exposure to mycotoxins is not usually identified as a risk factor present in occupational settings. This is probably due to the inexistence of limits regarding concentration of airborne mycotoxins, and also due to the fact that these compounds are rarely monitored in occupational environments. Despite the optimal conditions for fungal growth and, consequently, for mycotoxins production in all the waste management chain, only a few articles were dedicated to study occupational exposure to mycotoxins in this occupational setting. Aim of study: A study was developed in Portugal aiming to assess occupational co-exposure to mycotoxins in the waste management setting.

GFRP waste reinforced polymer mortars: a new waste management solution for GFRP scrap material

To date, glass fibre reinforced polymer (GFRP) waste recycling is very limited and restricted by thermoset nature of binder matrix and lack of economically viable enduse applications for the recyclates. In this study, efforts were made in order to recycle grinded GFRP waste proceeding from pultrusion production scrap, into new and sustainable composite materials. For this purpose, GFRP waste recyclates, a mix of powdered and fibrous materials, were incorporated into polyester based mortars as fine aggregate and filler replacements, at different load contents (between 4% up to 12% of total mass) and particle size distributions. Potential recycling solution was assessed by mechanical behaviour of resultant GFRP waste modified polymer mortars. Test results revealed that GFRP waste filled polymer mortars present improved flexural and compressive behaviour over unmodified polyester based mortars, thus indicating the feasibility of GFRP waste reuse in concrete-polymer composites.

Life cycle analysis of zero waste management for Jonggol green city

A Zero waste management is believed to be one of methods to gain sustainability in urban areas. Take advantages of resources as enough as the needs and process it until the last part to be wasted is a contribution to take care the environment for the next generation. Reduce, reuse, and recycle are three simplesactivities which are until nowadays consideredas the back bone of zero waste. Jonggolgreen city is a new urban area in Indonesia with a 100 ha of surface area zoned as education tourism area. It is an independent area with pure natural resources of water, air, and land to be managed and protected. It is planned as green city through zero waste management since2013. In this preliminary period, a monitoring tool is being prepared by applying a Life Cycle Analysis (LCA) for urban areas [1]. This paper will present an explanatory assessment ofthe zero waste management for Jonggolgreen city. The existing situation will be examined through LCA and afterwards,the new program and the proposed green design to gain the next level of zero waste will be discussed. The purpose is to track the persistence of the commitment and the perception of the necessary innovationsin order to achieve the ideal behavior level of LCA.

Implementing a site waste management plan: a case study of a medium sized building contractor in Ireland

Construction and demolition waste management is becoming increasingly important on construction sites as landfill space in Ireland is rapidly depleting and waste management costs are rising. Due to these factors waste management plans are seen as a good response to minimising waste on site and this thesis aims to investigate how to implement such a plan on a practical case study as well as investigating the legislation regarding construction and demolition waste along with market availability for the reuse of the waste. Main contractor surveys were also carried out in order to gain a better understanding of current attitudes within the industry and these surveys are analysed in chapter five. A survey was also carried out among sub-contractors but this survey has not been used for this thesis as the study is on-going. The primary aim of this thesis is to examine the waste hierarchy opportunities that are available for construction and demolition waste in Ireland and to examine the effects of management strategies on construction and demolition waste reduction at the project level. A partnership was developed with Carey Developments Ltd in Co. Galway and an analysis of their waste management practices was undertaken. The primary case study will be the ‘Taylors Hill’ project in Co. Galway where work commenced in March, 2012. The secondary aim of the thesis is to develop specific waste minimisation strategies for the company and to develop a training tool kit for use on site.

Health Impact Assessment and Waste Management with particular reference to Incineration: An introductory paper

This introductory brief has been written as a response to a request for information on HIA and waste management, with particular reference to incineration. EU legislation forms the basis for much of Irish waste management policy. Waste Management – Taking Stock and Moving Forward (2004) sets targets for increased prevention and minimisation, encourages reuse and gives preference to recovery and recycling, which is in line with the EU’s Sixth Environmental Action Plan (2002). In the area of waste incineration, the Waste Incineration Directive (2000/76/EC) has been transposed into Irish law and sets operating requirements for the incineration of waste.
