Abstract

Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.

The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.

The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.

Abstract

Purpose

The purpose of the study was to utilize rohu deboning by-product to develop edible cutlets and to study its effects on quality and acceptability.

Design/methodology/approach

Fish cutlets were prepared with varying mince and by-product ratios (100:0, 75:25, 50:50, 25:75 and 0:100 per cent) and the effect of by-product inclusion on composition, cooking characteristics, texture and acceptability were studied.

Findings

Cutlets from control group had highest values for protein, fat, diameter reduction, fat retention and height increase (29.9, 14.9, 7.6, 78.3 and 31.9 per cent) compared to other lots. Highest values for cooking yield (p > 0.01), lightness and whiteness were (92.7, 35.4 and 31.2 per cent) found in cutlets from 100 per cent BP lot. Hardness and shear force increased with by-product content (p < 0.01) being maximum in cutlets from 100 per cent BP lot. Though all the cutlets were acceptable, low sensory scores were recorded for 75 BP and 100 per cent BP lots (p > 0.01). By-products can be incorporated up to 50 per cent into fish cutlets without negatively affecting the eating quality.

Research limitations/implications

Amount of by-product to be added was the limitation during the work. More by-product content in the cutlets resulted in low-palatability. Total calcium content in the cutlets need to be checked as calcium content per serving should not be above the regulations.

Practical/implications

In general, nutritionally rich fish deboning by-product is used for cattle feeding or discarded into dumping grounds causing pollution, nutritional, as well as economic loss to the farmers. The findings of this study will be helpful to develop nutritionally rich and edible food products from this deboning by-product. Incorporation of by-product into cutlets will allow the farmers to sell their products at lower prices without compromising the profits, which will improve the marketing as well as consumption.

Social/implications

Utilization of fish deboning by-product to develop edible cutlets helps in reducing the operational costs, pollution and efficient utilization of process by-products.

Originality/value

The work is completely original in nature. The results reported are unique and the outcome of the research has social applicability.

Abstract

Purpose

The purpose of this paper is to evaluate the market potential of food obtained from olive by-products. The marketing of such by-products (e.g. olive leaves and pulp) is a challenging opportunity for the sustainable development of the sector. Yet, consumer demand is still poorly understood. The paper contributes to filling the knowledge gap with an empirical survey of a sample of Italian consumers.

Design/methodology/approach

The authors provide an assessment of consumers’ willingness to accept (WTA) food from olive by-products. The authors collected structured questionnaire from a sample of 289 Italian consumers. The authors asked to consumers their willingness to try a variety of food products containing olive by-products, as a proxy for their WTA the products. In order to investigate the drivers of the average WTA, the authors used the information in the questionnaire to build four constructs of interest: technophobia, neophobia, perception of benefits and awareness about sustainable consumption. The choice of the constructs and the variables was driven by the existing literature.

Findings

The paper shows how the WTA food with olive by-products is a general attitude of the consumer, rather than product-specific choice. The results suggest that consumers perceive the use of olive by-products as a new technology for preparing well-known food products. The authors did not find statistical evidence of the wariness of olive by-products as new food products. Technophobia is the most important factor hampering the marketing of olive by-products.

Originality/value

The paper is a first attempt of exploring the topic of WTA food with olive by-products.

Abstract

The standard measures of effective protection calculate EPRs by reference to an activity′s principal product. In many activities by‐products which have a positive economic value are important. Revises the standard measures to allow for the incorporation of by‐products and uses an example to illustrate how their exclusion can impact on estimated EPRs.

Abstract

Purpose

Consumption of muscadine grapes and their by‐products (e.g. skins, seeds, wine and juice) is often discussed in terms of their alleged health‐ related properties (e.g. high content of resveratrol, phenolics and antioxidants). Almost no information, however, is available from an academic perspective on consumers' association with this food, including their knowledge, actual consumption of muscadines or by‐products they associate with muscadine grapes. This study seeks to add to the limited existing knowledge on muscadine grapes and their by‐products exploring these areas.

Design/methodology/approach

A sample of consumers from a Southern US town, where muscadine grapes are native, was chosen. A total of 189 participated completing a questionnaire.

Findings

Overall, respondents indicated familiarity with muscadine grapes and by‐products (e.g. wine, jams, juice), but predominantly the more mature respondents related much more to those by‐products than the younger consumer groups. Concerning muscadine wines, while 56.6 per cent of respondents were familiar with this product, and 45.5 per cent considered their consumption experience satisfying to very satisfying, 67.7 per cent either never buy them or seldom do so, suggesting very limited attachment with muscadine grapes.

Research limitations/implications

Choosing one single geographic location (a Southern US town) and the number of participants are two limitations of this study.

Practical implications

Given the importance of muscadine grapes and their by‐products for the Southern region, particularly culturally, traditionally and for consumers in general in terms of beneficial health‐related properties, an argument is made concerning the need to promote this ancient food. The role of the hospitality and tourism sector, government, agricultural and consumer groups is therefore suggested in promoting, marketing and other forms conducive to raising the profile of muscadine by‐products.

Originality/value

The study focuses on a food (muscadines) and environment (the Southern US region) that despite their cultural importance continue to be under‐researched – even ignored – by much of the contemporary consumer behaviour, hospitality and other literature.

The purpose of this paper is to investigate the effect of current carbon tax (CT) policy on organizations involved in a sharing network relation.

Abstract

Purpose

The purpose of this paper is to investigate the effect of current carbon tax (CT) policy on organizations involved in a sharing network relation.

Design/methodology/approach

For finding the CT and economic value of the industries connected in a sharing network model a multi-objective multi-integer linear model has been formulated. The data set of the case organization is used for computation. The formulated mathematical model is computed with the aid of GAMS optimization program.

Findings

This research paper demonstrates the effectiveness of the sharing network strategy in increasing the economic value and decreasing the CT for industries involved in sharing network. The CT value INR 3,012.694 for the industries in Scenario II which incorporates the sharing network is less than the CT INR 3,580.167 for industries in Scenario I without sharing network.

Research limitations/implications

The data used for the computation is based on a particular sharing network under investigation. The formulated mathematical model can be checked with similar sharing networks by varying the parameters.

Practical implications

This work can aid in gaining complete knowledge on the sharing network strategy which can uplift the resources and the monetary value of the non-efficient industries moving them towards sustainable and greener supply chain practices.

Social implications

The presented work can impact various industries in developing countries providing them with a strategy to enhance their resources and economic value by maintaining an amicable relation.

Originality/value

This work uniquely was able to validate economic feasibility and CT in accordance with the carbon footprint involved in sharing network. This sharing network also incorporates the concepts of circular economy and reverse logistics for showcasing a better strategy.

Abstract

Purpose

This paper aims to study the use of pumpkin pulp and its by-products in food formulation. Pumpkins are important and useful in the food industry. However, only the pulp is used, and the shell and seeds are wasted, which represents an important food waste.

Design/methodology/approach

A systematic review was performed by searching electronic databases relating to the physicochemical, textural and sensory effects of the pumpkin pulp and its by-products’ incorporation into foods. No human subjects were involved, and ethical approval was not required.

Findings

Pumpkin seeds and shell have been included in quite a variety of products. The primary effects on the physicochemical properties of bakery products, dairy products, beverages and snacks are the increase in energy, protein, iron, calcium, carotene content and textural properties (hardness, chewiness, snapping force and viscosity).

Research limitations/implications

Limitations comprise the heterogeneity of the studies included, which causes varied results.

Originality/value

It was evidenced that pumpkin is already included in food products, especially in bakery products. However, there are not many products where the shell and seeds are used. Therefore, it is a field to be explored, as these by-products have great potential both to enrich food products and to reduce food waste contributing to sustainability.

Abstract

Over the past decade, biofuels production in the European Union and the United States has boomed – much of this due to government mandates and subsidies. The United States has now surpassed Brazil as the world's leading producer of ethanol. The economic and environmental impact of these biofuel programs has become an important question of public policy. Due to the complex intersectoral linkages between biofuels and crops, livestock as well as energy activities, CGE modeling has become an important tool for their analysis. This chapter reviews recent developments in this area of economic analysis and suggests directions for future research.
