Supply of some materials and metals in the World is getting increasingly challenging. To deal with this issue, several organizations (e.g. European Commission) have composed a list of materials critical for the economy, in the list, 27 critical materials (CMs) are included. Furthermore, several actions have been proposed to tackle the problem, including recycling of CM from secondary sources. Global supply chains of raw CMs often rely on limited number of suppliers (e.g., China, Russia, Brazil, US). Since some countries have monopoly and regulate the supply of CMs, they can have big impact on the prices of CM. Therefore, the objective of this paper is to explore the possibility of scrap recycling, which can be used to meet some of the demand. To evaluate the amount of scarp that can be used for recycling, we propose a graphical optimization technique (pinch analysis). To show the applicability of pinch analysis and the amount of scrap that can be recycled, two examples are presented.
Contribution/ Originality
This paper contributed in the area of supply chains of critical materials. The methodology used in the paper is Pinch Analysis, which is a graphical optimization method. The methodology used can be useful to determine the potential recycling rates of scrap within supply chain of critical materials.

The objective of this paper was to determine the influence of gearing and corporate performance of non-financial firms listed on the NSE. The target population being 42 companies with 35 companies meeting the threshold for a balanced panel regression for the period 2008-2017. The study adopted longitudinal quantitative research design with random-effects GLS models. The corporate performance was assessed by ROCE and Q ratio while gearing was measured using leverage ratio. The findings reveal that the gearing is positively and statistically insignificant related with corporate performance of the listed non-financial firms at the NSE measured using ROCE and positively significantly related to Tobin’s Q. This paper commends the necessity to cultivate a worthy rapport with debt capital providers such as banking companies, and other financial institutions to benefit from easy acquisition of large sums of funds and enjoy the interest tax shields related to interest charged on debt finance.
Contribution/ Originality
This study contributes in the existing literature on the effect of gearing by long-term borrowing divided by firm’s capitalization thus capturing the financial risk in a firm from a long-term perspective which usually influences the investors’ choice of a firm to invest into.
