Discarded electrical and electronic equipment contains valuable materials, low value parts, and hazardous substances. There is a growing concern regarding the management of end-of-use equipment owing to the environmental concerns associated with discarding used devices. Electronic waste or scrap consumes valuable landfill space and may ultimately contaminate groundwater sources. In addition, replacing discarded components with new components typically consumes valuable virgin material resources. With the advent of the WEEE (Waste Electrical and Electronic Equipment) Directive, used electrical and electronic products are now being recovered in Turkey as a European Union (EU) candidate country, and several companies in Turkey have begun to recover latent value through disassembly and reuse/recycling of materials and components. To remain competitive, these companies must implement economical and environmentally responsible recovery processes. There are a number of research challenges associated with product recovery. This paper describes the current product recovery infrastructure in Turkey, and discusses future trends and drivers for successful product take-back.

In today’s business environment, different factors make product return and product recovery increasingly more important in order to recover value and increase the company’s profitability. In such an environment, where sustainability concerns and awareness of environmental responsibility in industrial production has considerably grown, reverse logistics (RL) becomes more relevant and, thus, its correct management using suitable information systems (IS) is fundamental. Nevertheless, today’s IS in general, and in Enterprise Resources Planning (ERP) in particular, are developed based on conventional logistic processes that do not contemplate the specific characteristics of RL. The main objective of this work is to analyze the functional requirements of an IS to manage product recovery processes that serve as a guide to develop a suitable ERP for RL. The research methodology has been conducted with a qualitative approach, through which the main specific requirements that an IS must meet to manage RL have been stablished, and a data model for the development of solutions to the requirements identified in an ERP system has been proposed. For the development in the ERP it is recommended to start with the requirement of RBOM (Reverse Bill Of Materials) management, since it is the most complex development and has a greater relationship with the rest.

Neurorehabilitation relies on core principles of neuroplasticity to activate and engage latent neural connections, promote detour circuits, and reverse impairments. Clinical interventions incorporating these principles have been shown to promote recovery while demoting compensation. However, many clinicians struggle to find evidence for these principles in our growing but nascent body of literature. Regulatory bodies and organizational balance sheets further discourage evidence-based, methodical, time-intensive, and efficacious interventions because practical needs often outweigh and dominate clinical decision making. Modern neurorehabilitation practices that result from these pressures favor strategies that encourage compensation over those that promote recovery. With a focus on helping the busy clinician evaluate the rapidly growing literature, we put forth five simple rules that direct clinicians toward intervention studies that value more enduring but slower biological recovery processes over the more alluring practical and immediate “recovery” mantra. Filtering emerging literature through this critical lens has the potential to change practice and lead to more durable long-term outcomes. This perspective is meant to serve a new generation of mechanistically minded clinicians, students, and trainees poised to not only advance our field but to also erect policy changes that promote recovery-based care of stroke survivors.
