Productivity and Characterization of Biomass Obtained from Pruning of Walnut Orchards in México

Walnut tree (Carya illinoensis (Wangenh.) K. Koch) is a plant species showing ecological, social, and economic importance in México. The objective was to determine biomass productivity characterize the raw material briquettes obtained from walnut thinning pruning. variables evaluated were total height (TH), fresh (FB) dry (DB) per hectare (kg ha−1). Briquettes made by using both orchards. Laboratory tests for original included moisture content (MC), ash (AC), volatile matter (VM) fixed carbon (FC), as well high heating value (HHV). Briquette studies also diameter (D), weight (W), length (L), volume (V), density (Ds), HHV. data analyzed descriptive statistics analysis of variance (ANOVA) under completely randomized design with factorial arrangement. Thinning pruning orchards provides 12 kg tree−1 (998 ha−1) biomass, acceptable levels AC ≤ 5%, FC (75 76%), VM (18.7 19.7%) HHV (16.2 16.7 MJ kg−1). briquette international quality standards fulfilled: MC≤ 10%, 5% > 18 kg−1. integrated use residues reduces management problems registered during nut production sustainable options generate bioenergy will be expanded.
