“…Utilization of incinerator residue needs to be done by reducing risks to health and the environment, one of which is to produce materials with environmentally friendly uses. Some of the potential fly ash used include raw materials for the production of geopolymers with a strength of 2-8 MPa [39], building construction materials like fine aggregate [17]; substitute for cement in the manufacture of concrete [40]; a mixture of brick products [35]; synthetic glass-ceramic mixture modified by glass recycling [41]; in some European countries, ash is reused for the manufacture of pavements, bridges and structural masonry [32]; the use of solid waste as much as 30% replacing fine aggregate (sand) with a mixed composition of 1:3 using Portland cement type I in the manufacture of paving blocks will produce a compressive strength of 17.19 MPa. [42,43]; mortar mixture by providing a cement mixer as a binder [44].…”

The thermal process is one of the processes used in the treatment of solid waste generated from the activities of health service facilities (hospitals, health centers, clinics). The risk in the incineration process is the ash produced, the ash produced contains hazardous and toxic compounds so management needs to be carried out according to Government Regulations Ministry of Health RI number 56 of year 2015 and Regulation of the Minister of Health No. 9 of 2019. The purpose of this study was to find out how to handle health service facilities’ waste ash following applicable standards and friendly to the environment. This research is qualitative descriptive research. The research was conducted at the Moewardi Hospital Installation section. Sources of data in this study came from primary and secondary data. Data collection techniques were carried out by collecting data through interviews with sanitation employees and incinerator operators, reviewing documents, and field observations. Waste that can be treated with an incinerator is waste generated in health service activities such as syringes, bottles/ampoules, infusion needles. Management of incinerator combustion ash is carried out based on applicable regulations. The utilization of incinerator ash needed to be an environmentally friendly and sustainable product.

“…Fang et al (2020) pyrolyze dried and pulverized medical waste to obtain pyrolysis oil that may serve as a future substitute for fossil fuels. Moreover, the ash recovered from the incineration chamber contains several heavy metals, including Ba, Zn, Ag, Cd, and As, which are considered sources of value-added products (Papamarkou et al, 2018).…”

“…The polymeric transition from para-wollastonite (β-CaSiO 3 ) to pseudo-wollastonite (α-CaSiO 3 ) occurs when temperature is above 1125 • C [1]. Wollastonite glass-ceramics possess outstanding characteristics, i.e., high whiteness, low moisture absorption, low thermal expansion, low shrinkage, and low dielectric constant, which are suitable for wide applications in ceramics, chemicals, electronic devices, dental implant, construction, and polymers [2][3][4][5].…”

The fabrication of well densified wollastonite with smooth appearance by direct sintering method is still a challenge due to the competitive behaviors between sintering and crystallization. In this study, the coarser glass frits with a size of 1–4 mm are subjected to heat treatment at different temperatures. An attempt of integrating differential thermal analyzer with a slag melting temperature characteristic tester was exploited to monitor the heat and geometry changes during the heating. The results showed that the addition of CaF2 can significantly promote the crystallization of wollastonite at 940 °C, while hindering the sintering ability. At higher temperature, the increase of CaF2 acts as flux and favors the formation of eutectics, leading to a decline in the precipitation amount of wollastonite. The predominated liquid sintering brought fast shrinkage. It was found out that high content of CaF2 narrows the dense sintering temperature range and results in uneven surfaces. In order to obtain wollastonite glass-ceramics with smooth appearance, the maximum content of CaF2 in sintering glass-ceramics should be limited to 2 wt.%.
