Among agricultural pesticides, herbicides comprise the most employed group in agriculture. The main function of these chemicals is to control weeds, weed competition reduces produc‐ tivity, without significantly impacting crop yield. Weeds tend to compete with crops by extracting essential elements from the soil, water, intercepting light and CO2, interfering in the culture development and affe...

It has been shown that biomass refinery (biorefinery) with Zero Emissions perspective could convert agricultural wastes into valueadded chemicals and materials. Agricultural and plantations wastes would become as main resources for biorefinery without soil degradation and needs of additional land. Biorefinery non-farm production cycle is crucial for job generation and poverty elimination in rur...
