Implications of Expanding Bioenergy Production from Wood in British Columbia: An Application of a Regional Wood Fibre Allocation Model

Energy has been produced from woody biomass in British Columbia for many decades, but it was used primarily within the pulp and paper sector, using residual streams from timber processing, to create heat and electricity for on-site use. More recently, there has been limited stand-alone electricity production and increasing capacity to produce wood pellets, with both using ‘waste’ from the sawmill sector. Hence, most of the low-cost feedstock sources associated with traditional timber processing is now fully employed. While previous studies model bioenergy production in isolation, we employ a transportation model of the BC forest sector with 24 regions to demonstrate that it is necessary to consider the interaction between utilization of woody feedstock for pellet production and electricity generation and its traditional uses (e.g., production of pulp, oriented strand board, etc). We find that, despite the availability of large areas of mountain pine beetle killed timber, this wood does not enter the energy mix. Further expansion of biofeedstock for energy is met by a combination of woody debris collected at harvesting sites and/or bidding away of fibre from existing users.bioenergy production from wood fibre; mountain pine beetle; competition for fibre

Bamboo properties and suitability as a replacement for wood

The utilization of bamboo as a manufacturing material is becoming globally attractive in the wood and wood product industries today. This is due to the numerous industrial applications and uses of the bamboo plant from its fast growth, availability, unique appearance and strength. Bamboo has been popularly known for its traditional uses such as poultry cages, vegetable baskets, incense sticks, skewers and chopsticks, woven blinds and handicrafts. Very little has been done on the industrial processing of bamboo into boards. Several authors have studied and reported on the utilization, processing and the properties of this emerging material as an alternative to the increasing decline of wood in the forest. This review aims to compare and contrast some of the works done on the advancement in producing laminated bamboo timber. The properties of bamboo and its laminated products attest to its potency in substituting wood. Bamboo utilisation has increased significantly in the wood and wood product industries, with adequate retooling in most processing firms in the sector. In line with the development and use of bamboo-laminated timber for the purpose of wood in furniture production, the creation of bamboo plantations on degraded lands will meaningfully support production and mitigate the degradation of forest

Laminated Veneer Lumber (LVL) sengon: an innovative sustainable building material in Indonesia

Laminated Veneer Lumber (LVL) is recently available in Indonesian markets. The veneers are majority from Sengon wood (Paraserianthes falcataria), which is a fast-growing timber species native to Indonesia. Their use in practice is limited to non-structural components since Sengon wood species has low engineering properties and less resistance to termite attacks. The LVL production introduced few years ago has significantly improved both mechanical properties and durability as well as has expanded its utilization into various structural components. This remarkable improvement has made LVL Sengon wood as an innovative sustainable building materials in Indonesia. This paper summarized a series of authors’ work conducted since couple years ago to initiate the utilization of LVL Sengon in structural components such as shear walls and floor systems as parts of a project to develop its design standard. In addition, creep behavior of this LVL is also highlihgted here as this phenomenon is essential for designers and engineers to anticipate their designs within their service life. In particular, the test results showed that addition of diagonal members increased both racking resistance and equivalent viscous damping ratio of the developed LVL shear walls. And the LVL floor model which is composed of built-up box joists and plywood sheathing remained liniear-elastic under bearing load up to 18.75 kN/2

Resource utilization practices and sustainable development at the Lake Chad basin

The paper examines the resource utilization practices of the Lake Chad in view of the need for sustainable development of the natural resources of the area, which are being recklessly exploited. The issues of obnoxious fishing practices, inappropriate agricultural practices, indiscriminate grazing, reckless fuel-wood harvesting, water pollution etc were discussed. There are clear indications that the current resources utilization practices are pushing the natural resources of the area beyond the limit of their regenerative capacity. This is traceable to institutional weakness and inadequate management strategies at the Lake Chad basin. Suggestions were made towards witnessing a change of attitude to resource use, exploitation and management strategie

The complex binder based on Portland cement andash-and-slag wastes from thermal power stations

Increase in the balance of boiler and furnace fuel of the energy sector of the Republic of Belarus the proportion of own energy resources (milling peat and wood chips) places priority on resolving the issues of utilization of ash-and-slag wastes and reducing the area of ash-and-slag disposal sites, which cause irreparable damage to the environment. A considerable amount of research has been devoted to the utilization of ash-and-slag wastes. There are more than 300 technologies of their recycling and use. Ash and slag wastes are used in the production of concrete, mortars, ceramics, heat and water insulating materials, road construction. The world experience shows the potential of 70-80% utilization of ash and slag, as, for example, in some European countries. However, the cost of the recycling of ash-and-slag wastes with the production and simultaneous neutralization of wastes can be higher than the cost of the production. One of the directions of the use of ash and slag wastes is the production on their basis of new types of complex binder that have increased strength and low prime cost. The replacement of a part of cement with active mineral additive allows to achieve significant saving of binder. The existing methods of the production of complex binders include the stages of joint or separate grinding of cement clinker and mineral additive with following mixing. Significant energy costs for grinding increase the cost of binder. In this regard, the development of the effective complex binder with the use of ash-and-slag wastes of the Belarussian state district power station in Orekhovsk using resource-saving technology is the actual research objective
