The Euterpe oleracea Mart. has great importance in the neotropical forestry economy. Its berry is a product of great commercial value used extensively for human consumption. Most E. oleracea researches evaluate its food features, however, its potential use for phytoremediation and stipe use remains unknown. This research aimed to assess the seedling’s phytoextraction potential and the structural chemical composition in the seedlings and mature palm trees stipes. We used the Energy-dispersive X-ray fluorescence analysis to determine the concentration of the chemical elements. E. oleracea seedlings showed a great phytoextraction potential for aluminum and iron. The aluminum seedlings concentration was four times higher than preconized as a hyperaccumulator species. Calcium concentration was lower than considered normal, which may represent an antagonism effect caused by the strong presence of aluminum and iron. The fast uptake and accumulation of the seedlings highlight the potential to use this species in phytoremediation programs.

Plywood panel has a promising market in Wood Frame Construction System. Like any wood-based product, it can suffer deterioration, and preservative treatment is imperative. The preservative treatment can be done directly on a pressed panel - a conventional method that supposedly causes a decrease in physical-mechanical performance - or incorporated into the production process, by the previous treatment of veneers to develop panels with durability and quality. We compared the performance of these two processes. Panels were produced with Pinus taeda L., using 360 g m -2 of phenolic adhesive in a double line, a pre-pressing and hot pressing for 20 minutes under 1.2 MPa pressure and 130°C and treatement on veneers and panels with CCA-C. Tests followed Brazilian standards. Panels with previous treatment had lower water absorption and swelling. Preservation of the veneers also promoted higher retention levels and better penetration of preservatives. Both treatments did not affect the mechanical performance.
胶合板在木结构体系中有着广阔的市场。像任何木制产品一样,它会变质,防腐处理是必不可少的。防腐处理可以直接在压板上进行——这是一种传统的方法,据说会导致物理机械性能下降——或者通过对贴面进行先前的处理,将防腐处理纳入生产过程,以开发出具有耐用性和质量的面板。我们比较了这两种工艺的性能。面板采用松木(Pinus taeda L.)制作,采用双线酚醛胶粘剂360 g m -2,在1.2 MPa压力和130℃下进行预压和热压20分钟,并用CCA-C对单板和面板进行处理。测试遵循巴西标准。先前处理的面板吸水率和肿胀率较低。贴面的保存也促进了更高的保留水平和更好的防腐剂渗透。两种处理均未影响其力学性能。

The present study aimed to characterize medium density particleboard manufactured with CCB treated particles of Pinus sp. wood specie and alternative mixed vegetal oil-base bicomponent polyurethane resin. For this, three different resin concentrations (10 %, 12 % and 15 %) were used in combination with the presence or absence of the CCB preservative, resulting in six distinct treatments. The particleboards were produced according the Brazilian Standard – NBR and evaluated according European standards – EN. The results met the requirements of NBR and EN. The technical feasibility of making panels with those materials used were proved and the quality of the product according to its performance were verified, indicating the possibility to use alternative bicomponent polyurethane resin from mix vegetal oil. Statistical analysis demonstrated that adhesive and preservative factors and the interaction between them were significant on physical and mechanical properties.
