Abstract
Purpose
The purpose of this paper is to point out some important elements that can be useful to minimize the impacts and the results can possibly inform business and policy makers about how to minimize the impacts associated to the municipal solid waste (MSW) collection.
Design/methodology/approach
The present work faces with the problem of transport, placing attention to the relationship of emissions from scenarios that has been selected between real systems of management.
Findings
The choices related to the typology of treatment has the same importance to the item concerning the correct localization of the plant for the implications related to the environmental pressure due to the transport of waste.
Originality/value
An important aspect that has to be considered in terms of MSW management is the stage of collection. The emissions generated from these systems can arrive to values that are of the same order of magnitude of emissions from combustion of waste in waste-to-energy plants according to some scenarios.

Abstract
Purpose
In the EU, over the past three decades, poultry production has been growing around the 5 percent per year. This increase determined a higher volume of livestock and poultry farming waste, which represents a potential renewable fuel suitable for waste to energy conversion. One way is through biological process such as the dry anaerobic digestion (AD). Tests normally applied for the measurement of the anaerobic biogas potential (ABP) are reliable, but not feasible as a routine analysis. This kind of test is expensive and time consuming (21-100 days). The purpose of this paper is to propose a rapid method for assessing the potential of biogas in anaerobic poultry manure, with the goal of helping the choices of operators of AD.
Design/methodology/approach
The Dynamic Respiration Index was calculated as “key parameter” in order to estimate the ABP, which provides important information about the biogas generation for the poultry manure. Furthermore, two dynamic respirometric approaches were considered developed in two Italian universities. The main difference between them is the control of temperature.
Findings
Calculate ABP through IRD is a useful method to determine the value of the potential production of biogas of different biomasses in a short time and assess which one is more productive.
Originality/value
The methodology presented in this study is fast (one-five days) and alternative method to determinate the ABP, above all for the operators of AD plant.

The purpose of this action research is to begin to assess to what extent organizations have in practice begun to make the shift towards triple bottom line (TBL) sustainability.
Abstract
Purpose
The purpose of this action research is to begin to assess to what extent organizations have in practice begun to make the shift towards triple bottom line (TBL) sustainability.
Design/methodology/approach
A definition of TBL sustainability is provided, and key elements of TBL sustainability considered necessary to success are identified based on current literature and public commentary. An assessment is made via published surveys and an action research study of how these components are being addressed now and for the future. The action research study involved the design and launching of a Zoomerang survey that was posted both in the USA and on international websites and blogs.
Findings
The synthesis from the research reveals a lack of a clear definition of sustainability which sets in motion a whole systemic dynamic. The data from the action research exemplify this dynamic. First, there is a pattern of adopting a short‐term focus and expediency in decision making. Second, problem solving favors the “quick fix” over thoughtful consideration and development of the key components for sustainability. The research may also lead to questioning the urgency of implementing the very complex systemic TBL sustainability at this time in view of widespread climate concerns, versus concentrating on the more straightforward carbon footprint reduction.
Research limitations/implications
A major implication is the pressing need to clearly define sustainability and its organizational implications. Organizations must then make the shift from a short‐term perspective to more of a long‐term perspective, such that the clearly defined sustainability concerns will be addressed. Research conclusions are based on limited published data and a single survey; further research is required to substantiate the conclusions.
Practical implications
Sustainability is making some inroads in organizations but far too many organizations are only “going through the motions” with predictable results for overall need for improvement. A cohesive, clear linkage among the defining characteristics of sustainability, and guidelines for implementation, are proposed in this paper.
Originality/value
This action research presents data on how sustainability is actually viewed and implemented in organizations, and suggests from a systemic point of view which critical components of sustainability are yet to be seriously addressed.
