Closing the plastic loop
Plastic recycling has become a hot topic. The seriousness of plastic pollution has forced itself upon us. Industry, indeed the world, needs to close the plastic loop. But we don’t know how yet. Industry and policy makers will have to mount a concerted effort that includes taxation of fossil carbon in chemicals and materials. In
Plastic recycling: urgent, but a major problem
Suddenly, articles on plastic recycling pop up everywhere. Spurred on the one hand by continued growth in plastics production; and on the other hand by the ever growing problem of plastic waste. Scientists foresee that in 2050, there will be more plastic waste than fish in the oceans – if present trends continue. Something needs
Mass timber, the new technology
A revolution has taken place in the construction industry: the development of mass timber, the technical term for industrial timber. It allows for the construction of innovative buildings. Mass timber as a construction material can now even outperform bricks, concrete and steel in terms of cost, sustainability and wellbeing. MaterialDistrict, a Dutch foundation, has published
Timber, the old and new construction material
The world is rediscovering timber. Thanks to new technologies that open up new constructive techniques; and to a better appreciation of sustainability. MaterialDistrict, a Dutch foundation, has published Tomorrow’s timber, a book that explores all aspects of building with it, from GHG emissions and fire resistance to design and costs. This is the first of
Plant biostimulation, a new chapter in agriculture
Plant biostimulation is a new approach to agriculture. So far, substances that assisted the farmer were fertilizers and plant protection products, each with a well-known chemical composition. Biostimulants on the other hand are mixtures of compounds and organisms defined primarily by their effects: their beneficial functions to grower, agrosystem and the environment. This is a
Energy autarky more difficult than expected
The Dutch Wadden islands aimed to attain energy autarky in 2020. They fail to reach that target. For in order to do this, energy production and consumption don’t just need to match over a year; they also need to match continually, whereas both production and consumption vary considerably over time. That is difficult to achieve.
EASAC: burning biomass often doesn’t reduce CO2 emissions
The European Academies’ Science Advisory Council (EASAC) urges the European Commission to base its carbon accounting on science and the real effects on climate. The present accounting rules favour energy from biomass. Whereas often, burning biomass doesn’t lower CO2 emissions at all. EASAC suggests a standard based on real emission reductions within 10 years. This
Review: biostimulants for sustainable crop production
This book is what a review should be all about: lengthy (365 pg), thorough, several tables and hundreds of references. Overall, this is a complete book on a highly relevant topic. Biostimulants: natural substances supporting vegetative growth, uptake of nutrients, tolerance to abiotic stress by roots and plant tolerance to drought and salt stress. Feeding
