From waste to food and bioinsecticides: An innovative system integrating Tenebrio molitor bioconversion and pyrolysis bio-oil production.

To achieve a waste-free clean production, the present study aimed to valorize an underused agroindustrial byproduct (rice bran) by mealworms bioconversion and produce bio-oil from pyrolysis of insect excreta (frass) as bioinsecticide. To reach the first goal, the suitability of rice bran (RB) versus standard diet, wheat bran (WB), was examined by determining feed conversion, growth performance, and nutritional profile of T. molitor larvae.

Low-loading Pt/β-MoC catalyst for ethanol dissociation. Experimental and theoretical characterization.

The adsorption and dissociation of ethanol on Pt/β-MoC with a low noble metal loading (0.1 wt%) is studied in the context of catalytic H production from alcohols. X-ray diffraction and experimental results indicate that Pt modifies the lattice parameters of β-MoC.
