Energy security and pollution are becoming critical issues in the context of climate change and the circular economy, calling for sustainable resources. Asteraceae species, commonly referred as the aster, daisy, composite, or sunflower family, are among the largest flowering plants with 23,000 species belonging to 1600 genera, and are a major source of biomass. Here we review botanical characteristics and applications of Asteraceae for bioenergy, remediation, nanotechnology, medicine, food and agriculture. Sunflower is the most used to produce bio-oils with a yearly production of 47 million tons. Sunflower is also used for phytoremediation of heavy metals such as cadmium, lead, uranium, and chromium. Artichoke, chicory, purple coneflower, and wormwood display medicinal potential with 27–103 bioactive compounds. Artemisia, calendula, and sunflower oil are precursors for cosmetic and perfume production. Asteraceae species exhibited high efficiencies of 90−96% for removal of remazol red, and reactive blue dyes. Asteraceae species are used for fabrication of nanoparticles, biochar, activated carbon and biocomposites. [ABSTRACT FROM AUTHOR]

Nowadays, some antibiotics including oxytetracycline have been widely consumed over the world due to the increasing demands for essential activities such as human therapies, and agricultural farming. However, a residual amount of antibiotics could accumulate, and cause many negative impacts on aquatic environments. Therefore, the removal of antibiotics from wastewater has paid greatly attention. Herein, we reported the use of cobalt-based zeolite imidazolate framework (Co-ZIF-67) crystals by the microwave-assisted method, and their application for oxytetracycline mitigation. Co-ZIF-67 was characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, and scanning electron microscopy analysis. For adsorption experiments, the effect of oxytetracycline concentration (10–50 mg/L), Co-ZIF-67 dose (10–30 mg/L), and pH (3–9) was studied using Box-behnken design, combined with response surface methodology. An optimum finding was proposed with concentration of 10 mg/L, dose of 24.9 mg, and pH of 6.4, which tested for 88.26% removal efficiency. Nonlinear kinetics and isotherms were applied to more insight into the essence of oxytetracycline adsorption. Monolayer maximum adsorption capacity was measured, at 122.9 mg/g. Intraparticle diffusion model suggest a two-stage adsorption process, which first 30-min stage was very fast. The outcomes indicated the uptake of oxytetracycline controlled by chemisorption, in which proposed the role of hydrogen bonding. Through a comparative study, Co-ZIF-67 is recommended as a competitive adsorbent for the treatment of oxytetracycline adsorption. [ABSTRACT FROM AUTHOR]
