Summary Recycling of waste material and production of biofuels are the thrust areas to modern technology. The basic idea behind this work is to regenerate waste silver from X‐ray films and to employ them in biofuel production from jatropha oil. Stable silver nanoparticles (Ag NPs) were prepared using Quercus infectoria (oak gall) and raw Camellia sinensis (tea) extracts. The synthesized materials were characterized by XRD, UV‐visible spectra, energy‐dispersive X‐ray analysis, and Fe‐SEM technique. The temperature of the reactions, weight hourly space velocity, and time of reaction decide the yield of biofuel, and the parameters were optimized over Ag NP catalyst. Apart from yield of biofuel, the proportion of gasoline fraction (C5‐C9) was also peer monitored. A maximum of 90% conversion of jatropha oil was converted into 85% biofuel with 76% selectivity toward gasoline over Ag NPs. Flash point, fire point, calorific value, cloud point, specific gravity, and viscosity of the gasoline were evaluated and correlated with ASTM D6751 standards.
