Process Modification of Pharmaceutical Tablet Manufacturing Operations: An Eco-Efficiency Approach

Abstract

Abstract:A process improvement in a tablet manufacturing process within a pharmaceutical industry was carried out based on an eco-efficiency approach. As it is one of the most energy consuming processes in the production line, the tablet manufacturing process was considered. It has the highest production volume with a complicated and long manufacturing product life cycle. Data were collected on energy inputs and emissions data for the stages of powder direct mixing, particle size reduction, and tableting. A straightforward approach was then used to analyze environmental impacts in terms of GHG emissions. Non-added value steps were removed from the product life cycle process, which has led to significant time and cost savings, as well as to a reduction in the emission. Annual economic savings have been achieved, a time reduction of approximately 71% was attained, and the reduction in GHG emissions and energy cost were 73.2%. The g CO 2 eq per tablet reduction has been calculated within the process improvement to be 2.06 g CO 2 eq per tablet instead of 7.71 g CO 2 eq per tablet.

Additive Manufacturing of Oral Tablets: Technologies, Materials and Printed Tablets

“…Oral tables can easily be carried by the patient, making them available when needed (on-demand administration). Despite these advantages, conventional tablet manufacturing methods include time-and labor consuming procedures, including a multitude of steps: (i) bulk powder material handling and mixing of excipients and active pharmaceutical ingredients (APIs), (ii) powder processing such as compression and wet or dry granulation, (iii) tablet compression and testing, (iv) tablet relaxation, (v) tablet coating, and (vi) tablet collection and handling [4][5][6]. Continuous (oral solid dosage) manufacturing (CM) enabled full integration of bulk powder handling to final tablet product, yet CM offers limited dose flexibility and tablet customizability [7,8].…”

Utilization of hydrogen as clean energy resource in chlor-alkali process

“…an average annual growth of 7.7%). Currently, the electricity tariffs are undergoing a reform process to remove subsidies, so as to be consistent with costs of supply and provide an adequate incentive to save energy for large consumers (MEMR, 2016) influx of refugees into Jordan coupled with increasing demand of energy and water resources have caused significantly increased economic burden in Jordan (Al-Addous et al, 2019;Al-Awad et al, 2018;Al-Hamamre et al, 2017;Hindiyeh et al, 2018;Jabr et al, 2019;Saidan et al, 2017Saidan et al, , 2018Saidan et al, , 2019.…”

A Composite Evaluation Model of Sustainable Manufacturing in Machining Process for Typical Machine Tools

“…These studies are mainly composed of the static quantitative modeling analysis and dynamic quantitative modeling analysis. In the traditional static modeling analysis, the carbon emission is usually quantified through the whole life cycle evaluation and carbon footprint [12][13][14]. Considering the dynamic characteristics of the machining process, Li et al [15] presented a carbon emission analysis model for electronics manufacturing process based on value-stream mapping and sensitivity analysis.…”
