title: Total site utility systems optimisation for milk powder production

authors: Walmsley, Timothy Gordon

abstract: This study applies the Total Site Heat Integration method, in conjunction with a detailed process and utility model, to investigate three methods to increase the energy efficiency of the utility supply system for milk powder production. Sequentially explored opportunities are: (1) increasing boiler efficiency through condensing economisers, (2) waste heat recovery from the chiller unit, and (3) Combined Heat and Power (CHP) for electricity production. The basis for the analysis is the anticipated future milk powder process design, which incorporates results from recent studies that have focused on improving the process design and integration of the heat treatment and evaporator systems and recovering heat from the spray dryer exhaust, which show a combined specific fuel consumption reduction of 29.6 % and a relatively small increase in electricity use of 4.5 %. To maximise boiler efficiency, the study concludes that a condensing economiser for the flue gas can be indirectly matched with heating fluidised bed air flows through the boiler condensate system, which results in specific fuel use reduction of 227 MJ/tp. Chiller waste heat can be upgraded and integrated as a heat source to replace the equivalent specific fuel use of 101 MJ/tp through integration with the site low temperature hot water loop. By designing the steam system to maximise electricity generation in a new turbine, results show that 51 % of the site’s electricity demand may be satisfied by CHP. The combined effect of implementing these three utility systems opportunities is a specific fuel use of 3,868 MJ/tₚ, of which 530 MJ/tₚ result from electricity production, and a specific grid electricity demand of 113.4 kWh/tₚ.

title: Incorporating indigenous values in corporate social responsibility reports

authors: Schneider, Annika Barbara Sabine

subjects: corporate social responsibility

abstract: Purpose– The purpose of this paper is to show how a major state-owned enterprise in New Zealand uses its annual report to promote the image of an organisation concerned with the local community including Māori, the indigenous people of New Zealand, Māori values and their relationship with the environment.
Design/methodology/approach – This longitudinal single case study of Mighty River Power Limited spans the period 2000 to 2009. It involves detailed examination of the narrative disclosures contained in the annual reports, including photographs, over the period of the study to determine whether Mighty River Power used the annual report to present a favourable image to the organisation’s stakeholders. Indigenous partnerships between the organisation and Māori trusts were also investigated to determine how these contributed to the corporate identity promoted in the annual reports.
Findings – The analysis found that annual report was used to promote the image of an organisation upholding the Māori value of kaitiakitanga as part of its social responsibility to the local community and environment. Māori partnerships and community environmental group sponsorship were featured extensively in the images and narratives, with specific reference to indigenous values.
Originality/value – This paper builds upon previous literature in the field of corporate social responsibility in annual reports and extends it to the state-owned enterprise sector in New Zealand, focusing specifically on the relationship between the entity and the indigenous community in which it operates.
