Dentistry aims to diminish its environmental footprint by adopting the 4R’s concept (reduce, reuse, recycle, rethink) and through the switch to eco-friendly home oral hygiene products.
This paper evaluated the environmental impacts of different agronomic practices for a
hemp seed crop grown in Mediterranean environment. The following agricultural variables have been
considered: seven monoecious hemp varieties(Epsilon68 (E68), Fedora17 (F17), Felina32 (F32),
Ferimon (Fe), Futura75 (F75), Santhica27 (S27), Uso31 (U31)), three plant densities (40, 80,
and 120 plants m−2
), and two levels of nitrogen (N) fertilization (50 and 100 kg ha−1 of N). Life cycle
The high energy consumption of the lighting installations in highway tunnels has become a hot topic in the last few years due to the high figures in terms of money, consumed energy, use of raw materials, emissions of greenhouse gases due to the remarkable number of manufactured elements, and maintenance, among others. In spite of the different strategies proposed up to date and their savings, the potential benefits of decreasing the maximum speed allowed in tunnels have not been considered in depth as a complementary measure yet.
