This study deals with the subject biomass estimation. The objective was to achieve the additivity of tree biomass components, which is defined as the compatibility among the component predictions and total tree biomass, using ratio estimates. The biomass estimation model was applied to black wattle trees in forest stands, which include a sample of 670 trees in an age range of 1 to 10.75 years. The adjusted model, in which the total biomass, or sum of predicted components, is a function of the stem volume multiplied by the Scalar Coefficients Proxy of Density, proved to be of great interest for biomass estimation and consistent when compared to the results obtained by WNSUR estimates (traditional method). The natural additivity of the tree biomass components was fully achieved, when modeling them by means of ratio estimation. Equations developed from the proportional behavior of the biomass components at different ages did not require the use of linear regression models and were obtained from calibration with the experimental data. The estimators resulting from these equations proved to be appropriate to make a generic model for correction of ratios coefficients at different ages.

Small and medium-scale biorefineries are processing facilities designed to produce a portfolio of value-added products with applications in different productive sectors. The Territory of the Southern Coast (TSC) of Bahia in Brazil has a high potential to provide agricultural and forest biomass for these bioindustries. This study focuses on quantifying the biomass of key agricultural crops in the TSC from 1999 to 2019, utilizing data from the Municipal Agricultural Production (MAP) survey conducted by the Brazilian Institute of Geography and Statistics (IBGE).

Research about patterns of aboveground carbon stock (AGC) across different tropical forest types is central to climate change mitigation efforts. However, the aboveground carbon stock (AGC) quantification for Brazilian cloud forest ecosystems along the altitudinal gradient is still scarce. We aimed to evaluate the effects of abiotic and biotic on AGC and the AGC distribution between species and families of tree communities along an altitudinal Brazilian Atlantic cloud forest gradient of the Mantiqueira Mountain Range, Southeastern Brazil.

A novel hierarchical porous biochar based on ZIF-8 volatile hard template with high-efficiency electrochemical sensing performance for trace determination of Ponceau 4R.

A convenient method is proposed using a heat-treatable volatile template to prepare hierarchical porous biochar (HPB). Litsea cubeba leaves and ZIF-8 served as carbon source and volatile hard template, respectively. The good compatibility between ZIF-8 and biomass facilitated their uniform dispersion, and the thermal decomposition of ZIF-8 created abundant pores in the HPB.

Overgrazing is the primary human-induced cause of soil degradation in the Caatinga biome, intensely threatening lands vulnerable to desertification. Grazing exclusion, a simple and cost-effective practice, could restore soils' ecological functions. However, comprehensive insights into the effects of overgrazing and grazing exclusion on Caatinga soils' multifunctionality are lacking.

Paper-based packaging materials have gained attention from academia and industry for their outstanding environmental sustainability advantages. However, they still encounter major challenges, such as low mechanical strength and inadequate functionality, hindering the replacement of unsustainable packaging materials. Inspired by the remarkable strength of trees provided by cellulose fibers and the water and heat protection of trees provided by bark, this study developed a new biomass-based packaging material (SNC-C) that combines strength, thermal insulation, and water resistance.
