ClearcutHow many trees can be saved?

Al Wong, Arbokem Inc., Vancouver, Canada

ABSTRACT. Growth in paper and paperboard consumption in the developed countries continues at the rate of 2 to 3% annually. Most of the papermaking fibres are sourced from wood harvested from the primary forests. Because of economic greed, the accessible supplies have diminished considerably during the past 40 years. The demand to increase forest harvesting rate remains unabated. Culturally-valuable and ecologically-important forests are being destroyed unnecessarily.

It is timely to re-examine the supply of papermaking fibres from a zero-base viewpoint, without technical prejudice. The obvious sensible approach is the reinforcement of the basic tenet: Reduce, Reuse and Recycle, and with the addition of a "4th R". The fourth "R" is replacement of traditional virgin wood fibres with other fibres. Replacement with agricultural cropping residues in paper manufacture, in conjunction with "reduce, reuse and recycle" practices would have a significant impact on "saving trees". (AK16963W)

Sequestering anthropogenic carbon dioxide through industrial usage of agricultural cropping residues

Al Wong, Arbokem Inc., Vancouver, Canada and Ed Hogan, Natural Resources Canada, Ottawa, Canada

ABSTRACT. Global climatic changes are being accelerated by excessive emission of carbon dioxide through anthropogenic activities. One major cause is the increased burning of coal and natural gas fro the production of electrical energy. Carbon dioxide sequestering could be conveniently effected through the use of surplus straw for the production of pulp and paper as well as building products. The sequestering period could be as much as 20 years. Increased production of straw on existing grain cropping could provide additional sequestering of anthropogenic carbon dioxide. (AK16820)

Using crop residues to save forests

Al Wong, Arbokem Inc., Vancouver, Canada

ABSTRACT. Agricultural cropping residues are the only readily available source of fibre for agri-pulp production. Its aggregate quantity of 260 million tonnes in North America could significantly reduce forest-based wood usage for paper manufacture, in real time. (AK15904; agri981.tif)

Agripulp - the third papermaking fibre

Alfred Wong, Arbokem Inc., Vancouver, Canada

ABSTRACT. The use of agricultural fibre for the manufacture of paper has been known for centuries. Today, most of the agricultural-fibre pulp production is in India and China. Agricultural fibre is used largely because these countries have no natural forests or have depleted their forest resources. In North America, there is a renewed public interest in the use of ordinary paper made from agricultural-fibre pulp.

During the past 3 years, Arbokem has created a new class of high-performance commercial printing and writing paper and newsprint. This agri-pulp paper embodies agricultural pulp fibres and recycled wastepaper fibres. The agri-pulp paper is priced to be affordable by the public at large. Agricultural fibre paper has finally emerged from the stigma of “high-price boutique paper” business in North America. (AK15858A)

New direction in industry development and environmental protection for non-wood pulp mills in developing countries

Alfred Wong, Arbokem Inc., Vancouver, Canada

ABSTRACT. For important economic and social reasons, non-wood pulping is practiced largely, on a small production scale, in developing countries. The sever water pollution problems caused by the operation of these small-scale pulp mills have been largely ignored until recently. It is widely recognized that the capital cost of eliminating pollution from these small pulp mills is considerable. Consolidation of small pulp mills into larger scale production units would result in substantial social hardship for many rural communities. The adequate continual supply of raw material becomes unmanageable. A large-scale pulp mill does not guarantee economic viability. It is timely to consider alternative ways and means to maintain community-size pulp mills without polluting the environment. Selection of appropriate process technology is critical. There are manufacturing technologies available to replace the conventional kraft/soda pulping and chlorine-based bleaching processes. For certain non-wood raw materials, it is now possible to maintain high strength and to achieve high pulp brightness (e.g., 85%) without any bleaching. With advanced process technologies, it may be economically and socially desirable to construct smaller-scale pulp mills on purpose to benefit a large number of communities. (AK8914)
