“…The accumulated CCR under the influence of rains can easily be washed away into soils, increasing alkalinity. There are a series of recent studies on carbide sludge utilization 39 in the chemical industry [40][41][42][43] and inorganic synthesis 44,45 . Other fields of CCR utilization involve CO 2 capture 46,47 , soil stabilization 48,49 , materials 50,51 and road construction 52 .…”

Industrial activity results in ton-scale production of calcium carbide and generation of a significant amount of calcium carbide residue (CCR), which is often disposed of in the environment as waste. CCR is an active chemical, and rain washes away alkali from sludge, changing the pH of soils and water and damaging the environment. In this work, we explored new opportunities for the utilization of CCR in view of the coming industrial uptake of digital design and additive technologies. Amazingly, CCR can be successfully used as a filler for the modification of 3D printed materials towards the introduction of hybrid organic/inorganic frameworks. A series of commercially available plastics (PLA, ABS, Nylon, PETG, SBS) were successfully used as matrices for CCR-based composite production with high CCR contents up to 28%. Tensile analyses showed increases in tensile strength and Young’s modulus of 9% and 60%, respectively. Moreover, in comparison with the pure plastics, the CCR-based materials better maintained the digitally designed shape (lower shrinkage). Importantly, CCR-filled materials are 3D printable, making them very promising components in the building sector. Considering the amount of already available CCR stored in the environment, this material is available in large quantities in the near future for hybrid materials, and anticipated opportunities exist in the additive manufacturing sector. The involvement of CCR in practical composite materials is equally important for environmental protection and reuse of already available multiple-ton wastes.

“…Padahal, bahan bakar fosil merupakan energi tak terbarukan yang jumlahnya semakin terbatas, sehingga energi ramah lingkungan dan terbarukan seperti biodiesel sangat dibutuhkan untuk menggantikan bahan bakar fosil [1]. Biodiesel merupakan salah satu produk hasil reaksi transesterifikasi antara minyak nabati/lemak hewani (trigliserida) dan mono-alkohol dengan adanya katalis, juga dikenal sebagai fatty acid methyl esters, adalah bahan bakar lebih bersih yang ramah lingkungan dan dapat memainkan peran penting dalam energi terbarukan [2]. Secara kimiawi, alkil metil ester dengan rantai panjang asam lemak dapat diproduksi melalui esterifikasi asam lemak atau transesterifikasi minyak nabati, lemak hewani dan minyak goreng.…”

Pemanfaatan batu kapur dari Pamekasan, Madura sebagai katalis heterogen pada reaksi pembuatan biodiesel dipelajari pada penelitian ini. Batu kapur dikalsinasi pada suhu 900 ºC selama 3 jam untuk membentuk katalis CaO. Katalis CaO yang terbentuk dikarakterisasi menggunakan difraksi sinar-X (XRD), spektroskopi inframerah (FTIR) dan Scanning Electron Microscopy-Energy Dispersive X-Ray Analysis (SEM-EDX). Proses transesterifikasi dari minyak nyamplung dilakukan dengan rasio mol minyak terhadap methanol sebesar 1:16 pada temperatur 60 °C selama 1 jam dengan katalis CaO sebesar 4 % (w/w). Hasil analisis GC-MS diperoleh yield biodiesel sebesar 54% dengan konversi sebesar 49%.

“…This will reduce the prices of alternative sources of oil that is presently being used for commercial biodiesel production. Studies have shown that nano-catalysts such contain CaO, Al2O3, K2O, SiO, and other compound derived from agricultural solid wastes are excellent heterogeneous base catalysts for the transesterification of oil to biodiesel [17][18][19].…”

As a result of global urbanization and modernization, the use of petroleum (fossil fuel) is on the increase and there are growing concerns among stakeholders in the oil and gas industry over the depletion rate of petroleum reserves and its rising cost. The conversion of readily available sources of biomass to produce different types of biofuels to address the future energy crisis is one of the preferred attractive choices. Biodiesel is generally produced by the transesterification reaction of vegetable oils, waste vegetable oil or animal fats in the presence of a suitable catalyst. The choice of biodiesel as a preferred renewable source of energy was based on its biodegradability, non-toxic, lower emissions, sulphur free, low levels of polycyclic aromatic hydrocarbons (PAHs) and their nitrated compounds. This alternative source of energy is environmentally friendly and could be used in the existing diesel engines with little or no modifications. This will reduce the world's dependence on fossil fuels that are non-renewable with the attendant environmental benefits to mankind. However, the use of these edible vegetable oils will put pressure on the food uses of such oil which will result to fuel-food crisis in the future. This impending crisis can be readily averted by exploring non-edible crops/agricultural waste biomass that can be grown or harnessed domestically and capable of producing oils as valuable raw materials for the emerging industry. A free fatty acid (FFA) lower than 3% is necessary to carry out the base catalysed reaction to end. For biodiesel production, the higher the acid value of the oil, the lesser the conversion efficiency hence the need for esterification process. Papaya seed contains 27.3% to 28.3% protein, 28.2% to 30.7% lipids, and 19.1% to 22.6% crude fibers, it is not economically used. The majority of seeds are produced as residues and discarded as agricultural waste during fruit processing, generating environmental issues. Oil is abundant in papaya seeds (13.9% to 40.0%), which is rich in monounsaturated fatty acids and beneficial phytochemicals as tocopherol, carotene, and phenolics. This provides information on how to reduce pollution and make waste seeds lucrative. As a result, the CPSO is receiving an increasing amount of attention.
