How supply chain choices affect the life cycle impacts of medical products

Abstract

The natural resource based view (NRBV) of organisations suggests that there are two main models used by businesses to achieve short-term sustainability outcomes. They are the product stewardship and pollution prevention models. Here is the case of a New York-based wholesaler of medical supplies. The business aims to develop a more environmentally sustainable supply chain for one of its products -an emesis basin. The emesis basin is currently only offered in high-density polyethylene (HDPE) plastic, which has negative effects on the natural environment. This study aimed to assess how the focus of the business' new business model might affect the overall life cycle impacts of this product. To achieve this, we compared the environmental impacts of the conventional product (Scenario 1-an HDPE basin) with equivalent products supplied via pollution prevention (Scenario 2 -a bioplastic basin) and product stewardship (Scenario 3 -green supply chain management and improvements) scenarios, as well as a combination scenario (Scenario 4). The results show that, in line with expectations, the pollution prevention option -switching to a bioplastic product -has the lowest environmental impacts. Unexpectedly though, the product stewardship option had a greater impact on the natural environment than the conventional HDPE, business-as-usual option. We suggest there may greater environmental gains to be obtained by focusing on one's core business, than by extending influence to the entire supply chain. KEYWORDSNatural resource-based view (NRBV); Life Cycle Assessment (LCA); sustainable supply chains; medical supply sector HIGHLIGHTS  Four scenarios comparing conventional and bio-plastics considered  Bioplastic product has lowest environmental impact (pollution prevention scenario)  Supply chain changes (product stewardship) have higher impact due to transport fuels  There are benefits to focusing on core business over supply chain integration  We support deeper inclusion of medical supply industry in sustainability discussion Word Count: 8,082ACCEPTED MANUSCRIPT 2

The carbon footprint of the Chinese health-care system: an environmentally extended input–output and structural path analysis study

“…Since the carbon footprint is largely dominated by purchased medical products and services, supply chain choices are important in reducing the carbon footprint; eg, switching to bioplastic products. 33 Furthermore, using reusable medical products could reduce GHG emissions from both production and waste disposal. Hence, it is necessary to re-examine the design of medical devices in light of recycling or partial recycling requirements.…”

Biobased foams for thermal insulation: material selection, processing, modelling, and performance

“…[1][2][3][4] Besides being more sustainable, multiple studies show that replacing petroleum-based materials with biobased alternatives signicantly reduces environmentally harmful emissions. [5][6][7][8][9][10] Additionally, biobased materials are oen biodegradable, thus reducing landll waste accumulation. 11,12 Development of biobased foams has realized signicant advancements in recent years utilizing a multitude of materials and foaming methods.…”

The role of firm-internal corporate environmental standards for organizational performance

“…At the core of the NRBV are the strategies of pollution prevention and product stewardship (Gabriel et al 2018). Pollution prevention seeks to reduce emissions, effluents, and waste (Hart 1995, p. 992), so it may save the costs of installing and operating end-of-pipe technology, increasing efficiency through cost minimization or profit-maximization (Hart 1995).…”

“…Firms that pursue a product-stewardship strategy widen the scope of their environmental activities beyond their own firm towards an integration of stakeholders (Maas et al 2014). Therefore, while the key outcome of pollution prevention is continuous process improvement within the firm's boundaries, resulting in reduced costs, the key outcome of product stewardship is stakeholder integration across the supply chain, with the goal of pre-empting competition (Gabriel et al 2018). Following the logic of the NRBV, firms must work continuously to develop these "green" strategic resources to be competitive (Aguilera-Caracuel et al 2012;Hart 1995;Maas et al 2014).…”
