in order to make good quality lumber, good quality wood chips are needed, not chips do anyhow like combustible wafers ... which does not prevent there being ways to put common to grind any wood and sort the best to manufacture aglomerated wood and steer the rest as fuel

but is aglomerated wood a good ecological product? it is expensive in energy because of the amount of glue that it contains and it lasts less than real wood tree board

solid wood construction, board and beams can be cheaper than concrete or steel ... osb is more expensive to m2 than sheet metal ...

Oh, you know, a slab OSB put away from the water ... it can last several centuries. And it isolates.

I make insulations with OSB slabs placed on 60 x 40 mm rafter, I put thin aluminum insulation in the hollow space. I think it will bury me and my descendants or future owners.

Maybe in manufacturing, the glues have gray energy, but if it saves heat afterwards, the CO2 balance can be very positive.

yes of course osb or other aglomerate can last a long time in the dry ... but it falls in ruins at the slightest humidity, while real wooden board can be wet without falling into ruin ... so I do not build anything in ordinary osb or plywood ... I only want osb3 or marine plywood ... and I prefer old wooden planks!

I see piles of chipboard furniture that took water between 2 removal: it is quickly out of use ... real wooden furniture is more solid ... and when these pieces of furniture in aglomeré are damaged, no one dares to use them in heating ... it must be said that it burns badly ... but crushed and mixed with other wood crushed it burns well

The particle board factory near me has not used round wood (forestry) for several months and now only consumes "related" products: sawdust, chips, slabs, short cuts and various * ...

* In the various are probably a lot of chips, because sawmills hardly produce slabs with the "slabbers" ** which directly grind what corresponded to the slab.
**Slabber: combination of a circular saw blade and a shredding disc.

SPIE Industrie & Tertiaire - Industry division is about to complete the electrical installations, supervision, fire detection and video protection of the future biomass cogeneration plant of Chartres Métropole in Gellainville. This installation will supply nearly 17 homes with electricity and heat the equivalent of 000 homes. Undertaken at the initiative of Chartres Métropole, the construction of this new biomass cogeneration plant is part of the modernization and extension project to new beneficiaries of the urban heating system of the agglomeration.
Selected through a call for tenders launched by Cabinet Merlin (prime contractor), SPIE Industrie & Tertiaire - Industrie division was thus entrusted with operations relating to high voltage, low voltage and low current electrical installations, as well as 'automation and supervision (video protection and control of the device) of the power plant, for an amount of 1,9 million euros.

Biomass, a new source of energy for Chartres Métropole

The new plant will use 25% woodchip and 75% Class B wood, recycling wood lightly treated with paint or varnish.

The heat produced by burning the wood will be sent to a steam turbine, which will turn it into electricity, but most of this heat will be injected into the district heating network. The biomass plant will replace the existing gas boiler, which then only supports the biomass.

The plant, which has a Leroux and Lotz boiler from 26 MW and a steam turbine developing 8 MWé, is expected to produce 70 GWh of heat per year, equivalent to the needs of 6 000 housing, and a volume of electricity to power 17 000 homes.

SPIE, multi-technical service provider

SPIE intervened in macro-lots on three lots of the market (biomass handling, boiler system and utilities of the steam circuit) with the following services:

connection to the high voltage network 15 000 volts of the turbine,
supply and installation of an 10 MVA step-up transformer and 2 auxiliary transformers of 2 MVA,
automation of common equipment,
deployment of a supervision software to control the installations from a control room with a possibility of 200 views on screen,
implementation of low-voltage fire detection and video protection.
The studies began in September 2017, for an end of construction scheduled in July 2018. Commissioning of the new plant is scheduled for November 2018. About twenty employees are mobilized on this operation.

The SPIE group is 46 500 employees in the world, including 19 000 in France, who have been involved in more than 450 implantations. Consolidated sales in 2017 of 6,1 billion euros.

there is biomass available to make fuel ... the big mistake is not to use it and let it go in smoke in a forest fire!

if we exploited better, we would have squared off the California band cut to the ground and no forest fires could be spread over surface areas like at present

the problem is the same all over the world ... to protect the forest is not to cry like idefix when cutting a tree ... it is to share the fire in a useful way ... to cut or to use part of the wood so as not to let the whole thing burn!

and organize it all over the world ... the hottest and dryest countries do not need firewood ... you have to transport it! it's no more stupid than carrying oil

it is better to transport fuel wood to leave oil at the bottom of the wells

the use of fuel wood also solves another problem: non-recyclable plastic waste: it burns very well when it is mixed in small proportion with wood chips ... there is a whole organization to create!

Firewalls exist in the Landes and are effective, even if the forest management of this massif is very questionable. It is relatively easy in flat terrain, but would be much more complicated to implement in the Massif des Maures or in Var ...
You write:
the hottest and dryest countries do not need firewood ...

On the contrary, the need for cooking fuel is one of the important factors of deforestation, often via the manufacture of charcoal which, by increasing the energy density (at the cost of a waste of wood) makes it possible to go for it more further away from the major centers of consumption.
The theoretically renewable nature of wood, but only in some cases and the time difference between consumption and regrowth, makes the hypothesis of carbon neutrality (vis-à-vis oil) hazardous.

The 2019 edition of the call for biomass boiler projects in companies is launched


Environment Magazine the 18 October 2018

Last October, the French Environment and Energy Management Agency (Ademe) launched the 15 edition of its call for projects (Biomass heat industry and tertiary industry "(BCIAT). to announce the winners of the 2019 edition.

For the 2019 edition of this BCIAT call for projects, two closing dates are announced: the January 31 and the next 23 May. "For heat production facilities, special attention will be paid to projects that replace fuels that emit a lot of greenhouse gases (such as coal)," it says. The financial assistance provided by the Ademe Heat Fund will be evaluated according to the size of the project and its economic profitability.

Seven winners for the 2018 edition

For its 2018 edition, Ademe's BCIAT call for projects includes seven winners for a total production of 464 GWh / year and for a total amount of aid of 26,6 million euros, as well as 70 million euros investment:

- Drôme Ardèche Enrobés (materials) in Auvergne Rhône-Alpes, for a production of 11,9 GWh / year
- Voltinov - Alsapan (wood) in the Great East, for a production of 6,6 GWh / year
- Capdea (dehydration of agricultural products) in the East, for an annual production of 29,9 GWh
- Engie - Novo Nordisk (pharmacy) in the Center-Val de Loire, for a production of 23,1 GWh per year
- SAS Soka (materials) in Brittany, for an annual production of 37 GWh
- Guyot Environnement (dairy) in Brittany, for a production of 57,6 GWh per year
- Taranis du Rouvray (Paper / cardboard) in Normandy, for an annual production of 237,6 GWh per year.

"Increasing the use of wood waste as fuel"

"This edition confirms the trend of the past two years in increasing the use of wood waste as fuel. This share amounts this year to about 60% of total biomass consumption for all projects, "said Ademe in its statement.

It is also recalled that "since 2009, the call for projects BCIAT has allowed the realization of 106 facilities and the production of more than 6 TWh / year covering a variety of needs (production process, heating ...) and sectors of activity (agribusiness, chemistry, etc.) »

Is forest wood a renewable energy? Citizens from seven countries are suing the EU to try and prove no.

According to the complainants, "to consider that biomass energy has a neutral carbon footprint runs counter to the evidence provided by science" which demonstrates that burning wood for energy generation emits 1,5 times more CO2 than coal and three times more than natural gas. The European Commission declined to comment and merely pointed out that it was up to the EU Court of Justice to comment on the admissibility of the case.

Last year, the EU adopted a revised version of the Renewable Energy Directive, committing its Member States to reach the threshold of 32% renewable energy by 2030. This threshold is considered a central element of the EU's target to reduce its carbon emissions by 40% for the same year.

The complainants argue that in describing forest biomass as renewable energy, the EU infringes Article 191 (1) of the EU Treaty on the Functioning of the EU, which provides that the Union's environmental policy contributes to "the preservation, protection and improvement of the quality of the environment [...] and in particular the fight against climate change ".

According to them, the directive is all the more dangerous for the climate as it would encourage deforestation in the United States to meet the demand for wood pellets in Europe. They highlight prejudices to their health, livelihoods, communities and cultural traditions due to logging, pellet production and biomass energy. https://www.euractiv.fr/section/climat/ ... ble-energy
I understand those who are against Europe for suicidal decisions like that.
The wood should have remained for the heating of private individuals, not used to excess to make electricity.
In addition, we will need biomass to store carbon in soils in sustainable agriculture.
