Poplar and its advantages
Wild poplar woods have always existed but it is the concept of “short rotation tree” (fast growing trees cultivation) to have raised, over the last 30 years, the interest in the whole world on poplar. It is indeed in Casale Monferrato, that the Research Centre for plantation trees has created the “I-214 Clone” the most cultivated poplar variety worldwide for industrial purposes. Poplar cultivation is the most advanced form of tree cultivation in the world. The use of the most innovative cultivation techniques aimed at make the most of its natural strong points granting constant quality and the respect of the most severe environmental standards.
Poplar wood shows a series of features which make it suitable to be transformed into plywood and blockboard panels as:
- Light weight – Poplar plywood has a specific weight of 450 kg/m3 +/- 10%
- Light and plain colour – Unlike other wood species poplar logs allow to obtain wide white and plain sheets.
- Versatility – Poplar has an excellent ratio between specific weight and mechanical features. Despite of its light weight, the modulus of elasticity and the screw strength make of poplar a suitable wood to be used in the furniture sector (its first end use) as well as structural component as an alternative to other material where the CE2+ certification is also available.
- Ease of work – Despite its high resistance, Poplar is a mild wood, it is therefore easy to work and reduces tools consumption.
Poplar is also and above all environmentally friendly
- Like all fast growing species Poplar has an excellent capacity to purify air. The faster and the bigger the tree grows, the faster and the higher it releases oxygen and holds carbon dioxide. A growing poplar absorbs 70-140 litres/hour from the atmosphere and releases the same quantity of oxygen. What is more the carbon dioxide contained in a grown tree remains stored in the logs and afterwards in the panels obtained from them (Carbon Sink).
- Poplar can purify water, as it absorbs polluted water from the soil and releases it purified into the atmosphere holding the harmful toxins into the wood or into the leaves. Once they join the soil again they are already decayed or they are already combined with other organic components thus highly reducing the pollution of the aquifer.
- Poplar works as a retaining element for soil erosion and desertification, it improves biodiversity and conserves the environment.
- Poplar is a renewable source and can be used to replace material with a high carbon dioxide content.
- Poplar trees come from cultivations managed through strict environmental standards, they are not cut down from virgin forests.
- Poplar cultivations are located next to the production sites, therefore exhaust emissions caused by transport are consequently strongly reduced.
- Poplar wastes are an excellent biofuel, therefore the tree is used in its whole (no production waste).
The Bonzano Industries’ panels are even more environmentally-friendly has poplar plywood and blockboards from both IBL SpA and Derula Kft can be certified PEFC™. Derula can also supply FSC® poplar panels.
The Bonzano Group carries on with its sensibilisation campaign to actively protect the quality poplar. Indeed the Group belongs to the International Association Pro-Populus. Born in 2008 the Association is unique in its genre as for the first time ever it gathers poplar manufactures, promoters as well as industrial users in their various sectors (panel production, packaging and energy). The association aims first of all to raise poplar to the role of strategic raw material. The birth of this association was fostered by the CEI Bois, the European Confederation of the Wood Industries, where it is also located.
