Full textAccording to Québec’s Règlement sur les matières dangereuses, wood residues containing resin are likely to be toxic residual dangerous matters because of their formaldehyde content. The management of these residues is problematic for the secondary board manufacturers because the majority might not operate a combustion boiler with high enough power to burn board residues in conformity with regulatory requirements. The recovery of these residues could be possible, but no decision can be taken without knowing the nature of the residues. The objective of this study is to characterize the residues coming from the secondary board manufacturers in the province of Québec in order to find opportunities for recuperating, recycling or disposing of these residues. A survey of secondary board processing plants has been conducted to draw a picture of the disposal of residues. A mail questionnaire was sent to a sample of plants within each industrial sector. The five points of contact method was applied, yielding a response rate of 32%. A quantification of the residues was made and the data was used to extrapolate the results to the whole of Québec industry. A segmentation of the results according to the size of the plant or to the industrial sector was made and significant differences were found between classes regarding the management, the use and the contamination of the residues. The majority of secondary board manufacturers send their board residues to landfill sites. This is the case of most small size mills. The survey indicates that 30 percent of the mills have experienced serious problem in managing these residues and they have already tried to find a better solution to dispose of them.

Full textThe objective of this work is to recycle secondary sludge (SS) and explore its potential as co-adhesive for Urea-formaldehyde (UF) adhesives used in particleboard manufacturing. We hypothesized that it is possible to use the SS as co-adhesive for the manufacture of composite panels made of wood particles. First, we modified UF resin by the addition of SS to synthesize a new co-adhesive. The results of the first approach showed that the curing time of the resin is very short and it was concluded that this approach is not applicable on an industrial scale. Although the first approach is rejected, some conclusions can be drawn: 1) The characteristics of the SS vary with the papermaking process, the plant and the sampling time. 2) Dynamic scanning calorimetry (DSC) thermograms show that the influence of SS on UF cure is noticeable. 3) Nuclear magnetic resonance (NMR) showed that there is an optimal ratio between the chemi-thermo-mechanical pulping CTMP (B) SS and UF. The second approach is to add SS in-situ in the process of panel making in different proportions. This approach is technically feasible and has been tested with SS from the three different sources (TMP, CTMP and Kraft). Preliminary trials were done. Then, a final experimental dispositive was set up to evaluate the potential of SS from these different processes as co-adhesives. Factors are the UF resin content (3 levels), the SS source (3 sources) and the proportion of SS (3 proportions). There was an optimal ratio of SS/UF according to the values of internal bond (IB) of particleboards from the preliminary trials. SS cannot be used as an adhesive alone for particleboards. In general, results of this study indicated that the use of SS from three different pulping processes as co-adhesive have several advantages including the possibility of manufacturing particleboards at reduced urea formaldehyde (UF) resin content and wood particles content, value-added utilization of pulp and paper sludge and, especially, reduction in formaldehyde emissions. The reduction of formaldehyde emission with the recycling of SS as co-adhesive has the most significant environmental benefit.

Full textWastes from the French wine industry are traditionally treated and upgraded in distilleries. This work deals with the study of an industrial-scale valorization of a final waste from distilleries: the spent grape pomace. Pomace from different French production areas were chemically characterized, in terms of condensed tannins and polysaccharides. An extraction process of condensed tannins has been optimized in laboratory and was then transferred to an industrial scale. Several extractions were carried out in three partner distilleries and chemical analysis (in terms of polyphenols, condensed tannins, sugars and inorganics) of the different isolated fractions were performed. Industrial extracts were used for the elaboration of the first particleboard whose adhesive constituted by 80% of grape pomace tannins and strengthened with a synthetic resin to satisfy the European standard for internal bond. These industrial extracts were also used to partially substitute a phenol-formaldehyde resin for the production of particleboards. Different post-treatments were performed on the pomace extracts in order to increase their chemical reactivity toward cross linking agents. Filtration with a cut-off of 1 µm led to a slight improvement in adhesive performances, whereas acid hydrolysis of the extract have degraded it. An ultrafiltration process of the extracts at 5 kDa or at 1 kDa enabled to get much more reactive extracts and opened up prospects for the production of bio-based adhesives for wood

Full textThis thesis deals with the dimensional control, in industrial conditions, of large manufactured particleboards. Two principal problematics were broached: the mosaicking due to acquisition conditions and the measure of distorted circular forms. For the first problematic, a solution based on interest points search by hessian matrix combined with a local characterization by Census transform was revealed as an efficient method. The second problematic, due to the crumbly nature of the material and obstructions by the coating, is the measure of imperfect edge drillings. In order to compensate distortions, a multi-scale approach by active contours was developed. This one gives, in one pass, a set of approximations of the initial outline around a global scale factor. More regularized outlines are then generated more or less close to the original form following a second scale parameter. The estimator of obtained circular forms characteristics is done with a new estimator based on the Radon transform. Circle's tangents allow to find the center and the radius. The method is based on an accumulation principle in discrete geometry and discretized parametric fitting, giving a subpixel precision. This new approach is more accurate than classical estimators in the framework of distorted circles
