Un grupo de investigadores ha desarrollado un proceso para convertir los desechos vegetales de la agricultura y celulosa extraída de la madera en combustible de alta densidad para aviones, según un estudio publicado en la revista Cell Press.

"El avión que usa este combustible puede volar más lejos y transportar más que aquellos que usan combustible de avión convencional, lo que puede disminuir el número de vuelos y las emisiones de CO2 durante el despegue y el aterrizaje", argumentó el autor principal, Ning Li, del Instituto Dalian en China.

Metsä Group has renewed its strategic sustainability objectives. These 2030 objectives extending to 2030 cover all Metsä Group operations and are also mirrored across the supply chain.

Metsä Group’s target is to increase the amount of carbon stored in forests and its products. The amount of carbon in forests will be increased through expanding the area covered by Metsä Group’s forest management services by 30 per cent compared to 2018. The amount of carbon stored in products will be increased also by 30 per cent through investing in products that store carbon for a long period of time. In addition, biodiversity will be safeguarded through increasing the volume of decayed wood in forests.

Aunque para los científicos las resinas fósiles (ámbar), capaces de conservar insectos atrapados en épocas remotas, son una ventana abierta para descubrir la biodiversidad del planeta hace millones de años, el estudio, que publica la revista “Proceedings of the National Academy of Sciences (PNAS)”, ha vertido ciertas dudas sobre su rigor. La investigación, además, ha concluido que las piezas de ámbar no pueden representar la complejidad de la comunidad de artrópodos de los bosques del pasado.
