The rapid progress of the CPO industry in Indonesia is not in line with good waste management and utilization. Palm empty fruit bunch, as the first waste from the CPO production process in Indonesia, is mostly piled on the ground. Palm empty fruit bunch must be processed to reduce pollution and increase its use-value. This study aimed to convert oil palm empty fruit bunches solid waste through the gasification process using Indonesia’s natural zeolite into synthesis gas. Gasification takes place at 350–550°C by added 12.5% wt zeolite using a modified updraft gasifier. Good results were achieved at 550°C with a gas composition of 22.64% vol CH4, 29.22% vol CO, and 3.4% vol H2. The gasification efficiency is evaluated through carbon conversion efficiency (CCE) and cold gas efficiency (CGE). Both the highest CCE and CGE were found at 550°C by 95.74% and 81.65% respectively. The results showed that the gasification temperature has the greatest influence in driving higher carbon conversion to syngas and palm empty fruit bunches are very suitable for conversion into environmentally friendly syngas in the CPO industry.

Pure MCM-41 anchored benzene sulphonic acid (BSA/MCM-41), an efficient heterogeneous catalyst, was prepared for the synthesis of CL-20 from TAIW. The prepared catalysts were fully characterized by FTIR, XRD, TEM, TG, N2 adsorption techniques, elemental analysis and acidity tests. It was observed that the catalyst (BSA/MCM-41) retained the mesoporous structure like MCM-41, exhibited excellent thermal stability and high activity. Compared with a blank, the high catalytic activity promoted shorter reaction times by a factor of 3/5. In addition, this catalyst could be reused at least five times without significant loss of its catalytic potential. Moreover, the BSA/MCM-41 catalyst exhibited an optimal catalytic performance, with a high to excellent yield of CL-20 (92.5%) with a purity of 98.3%, under the optimum synthesis conditions.

Traditional drug design has been effective in the development of therapies for a variety of disease states but there is a need for new approaches that will tackle new challenges and complement current paradigms. The use of metals in medicine has resulted in several successes and allows for the introduction of properties that cannot be achieved by use of organic compounds alone, but also introduces new challenges that can be addressed by a careful understanding of the principles of inorganic chemistry. Toward this end, the unique structural and coordination chemistry, as well as the reactivity of metals, has been used to design novel classes of therapeutic and diagnostic agents. This review briefly summarizes progress in the field of therapeutics, from the earliest use of metals to more recent efforts to design catalytic metallodrugs that promote the irreversible inactivation of therapeutically relevant targets.
