Rubber extraction in the Amazon faces enormous ecological and economic challenges. We modeled the ecology (tree density and forest yields) and the production chain, including rents of the three major rubber products: Pressed Virgin Rubber (PVR), Liquid Latex (LL), and Liquid Smoked Sheet (LSS) from native forests and from plantations in Southern Acre, including the emblematic ChicoMendes Reserve. Our estimates show that, in native forests, tree density ranges from 0 to 4 trees/ha (average = 1.67 trees/ha), while productivity varies from 1 to 3 l/tree/year (average = 2.26 l/tree/year) with yields between 1 and 6 l/ha/year. Our model estimates a potential annual production of 890 tons of dry rubber in the 2.5 million ha of forests of Southern Acre (average=0.36 kg/ha/year). Rubber extraction in native forests is not economically viable without government subsidies. Mean Equivalent Annual Annuity (EAA) for LL is US$ 3.24 ha/year in a scenario with subsidies and of 75% of potential annual harvest. LSS from plantations reaches an EAA of US$ 270 ha/year if costs of formation are subsidized. Public subsidies or Payments for EcosystemServices are essential to sustain, at least temporally, rubber tapper identity ? an important Cultural Ecosystem Service of the Amazon. |

Residual wood fines were used as raw material to produce fast pyrolysis bio-oil in a pilot plant for furtherutilization as antifungal and hydrophobic agent for wood protection. Phenolic compounds derived fromlignin mostly composed the obtained bio-oil. Pinewood was impregnated with natural and diluted bio-oilaiming three different final loads. Scanning electron microscopy images revealed that the internal surfaceof the tracheids was coated by the bio-oil. Fourier-transformed infrared analysis showed no chemicalreactions between wood and bio-oil, while thermogravimetric studies stated changes in the thermalstability of the impregnated pinewood. The bio-oil impregnation proved to be effective to decrease thewater absorption and wettability of the pinewood. In addition, the bio-oil impregnated pinewood withlow load (7.95%) had decay resistance improved by 2.6 and 4.5 times against T. versicolor and G. trabeumfungi, respectively, meanwhile the highest bio-oil loading (81.3%) inside pinewood caused the mortalityof the whole fungal colony in the first days of test. |
