The results of the diagnosis carried out at the woodworking in the city of Belo Horizonte showed that the companies surveyed generated large volumes of MDF and solid wood (Corrêa et al. 2004). Therefore, these materials were used as a raw material for the development of the composite material. As already seen, most of the Brazilian furniture industries (74%) are microenterprises (Abimóvel 2006). In this way, the use of transformation technologies compatible with the reality of these furniture companies, both from a productive and economic point of view, was prioritized with the objective of making possible the reuse of wood and MDF residues by the woodworking companies themselves.
Wood
Published in Vasile Minea, Industrial Heat Pump-Assisted Wood Drying, 2018
The European Union’s wood-based industries cover a range of downstream activities, including woodworking industries, large parts of the furniture industry, pulp and paper manufacturing and converting industries, and printing industry. Together, some 415,000 enterprises are active in wood-based industries across the European Union; they represent nearly 20% of manufacturing enterprises across the European Union, many being small or medium-sized enterprises.
Chemical Hazard Communication
Published in Gary F. Lindgren, Managing Industrial Hazardous Waste, 2018
An evaluation of a chemical’s potential by-products or decomposition products must also be made. For example, chemicals such as carbon monoxide generated from the incomplete combustion of fuels or ozone generated during arc welding processes must be included in a chemical inventory. Wood dust generated by woodworking operations is also regulated under the HCS. MSDSs for gasoline or welding rods should provide information as to the hazards of decomposition products or by-products. If not, these by-product or decomposition compounds should be included in the inventory.
Evaluation of the influence parameters of Industry 4.0 and their impact on the Quebec manufacturing SMEs: The first findings

The digital performance evaluation process began in Quebec in early 2017 when the Ministry of Economy and Innovation (MEI) gave to different organizations the mandate of implementing a tool for measuring the digital performance. Since its deployment, the participating manufacturing companies have been receiving a grant from the government to cover the costs incurred by the process. However, to participate in such a project, companies must first demonstrate that they have made a strategic planning and have a certain level of organizational maturity. The 14 companies participating in this project operate in various sectors such as plastics, metal, electronics and electromechanics, woodworking as well as manufacturing of cabinets and components of wood. Figure 6 shows the distribution of enterprises by sector of activity.
Characterization of wood dust emission from hand-held woodworking machines
Published in Journal of Occupational and Environmental Hygiene, 2018
In the frame of this study, two types of hand-held machines were tested. We have selected four sanders and nine circular saws. Sanding is one of the most widespread machining procedures for woodworking, mainly of raw wood. It generates rather fine wood dust. Sawing is also an extremely widespread operation, used to cut both raw wood and chipboard. The dust created during sawing is of a different particle type from that issued from sanding and circular saws are very emissive machines.[5] The dust shape also differs. These two characteristics have an influence on the response of the sensors used during tests.[12] Wood dust morphologies induce a bias during the measurement of concentration with optical counters. The determination of the shape factors and densities of these dusts is not straightforward.[6,9]

Dust from wood products is a complex substance that varies considerably depending upon the tree species from which the wood is derived. Most human exposure arises from woodworking activities in construction or furniture building. ‘Furniture and cabinet making’ was examined in previous IARC reviews, and identified as a cause of nasal adenocarcinoma. Wood dust induces cancer of the nasal cavity, paranasal sinuses and nasopharynx. Evidence suggests that exposure to dust from hardwood trees is associated with a higher risk of cancer.
