moisture content before cooking in a continuous rapid di-
gester (20 to 40 min) at 60°C to 70°C without pressure.
Quality of pulp is similar to that of pulp from a conven-
tional sulphate process, yield is higher and energy con-
sumption lower.

tha as a raw material for pulp (A trema micrantha como
materia-prima para a producao de celulose). Acta Amazon-
ica. 3(3):45-50.
Sulfate pulping and bleaching trial results, fiber dimen-
sions, and the chemical composition of Trema micrantha
are given.
Rique, T.; Repetti, R.; Angelinetti, A.R. 1979. Inte-
gration of the quebracho extraction industry with the man-
ufacture of cellulose pulp (Integracion de la industria del
extracto de quebracho con la fabricacion de pastas celulosi-
cas). Instituto Forestal Nacional, Buenos Aires, Argentina.
Folleto Tecnico Forestal. 54:21.
Describes a study evaluating the use of Schinopsis bal-
ansae and S. quebracho-colorado for tannin extraction and
pulp production, using combined or separate treatments of
bark and wood. One scenario is to use sulphate or sulphite
treatment of quebracho logs followed by separate processing
of tannin-containing liquor and pulp. Results of an initial
trial were encouraging. The quebracho tannin industry in
Argentina is discussed.
Roda, A.W.; Lopes, C.H. 1978. Babassu–the wonderful
palm. In: USA, TAPPI (Technical Association of the Pulp
and Paper Industry), Atlanta, GA. Nonwood Plant Fiber
Committee: Nonwood plant fiber pulping. Progress Rep.
9:41-45.
Describes the manufacture of NSSC pulp from the Babassu
palm tree, which is satisfactory for use as corrugating
medium. The palm Orbygnia speciosa was pulped at Indus-
tria de Sacos de Papel SA in Brazil. Chipping, depithing,
and recovery of spent pulping liquors are discussed.
Rodrigues, W. A. 1972. Virola surinamensis and its uses.
Acta Amazonica. 2(2):29-47.
Describes Virola surinamensis giving taxonomy; general
botanical features; phenology; ecology; distribution; silvical
characters; phytopathology; leaf histology; wood anatomy;
traditional uses of seeds, bark, etc. for medicine, tallow,
and cattle fodder; and the physical, mechanical, and chem-
ical properties; and uses of the wood including suitability
for pulp and paper.

and its solution (La crisis mundial de la celulosa y el papel
y su solucion). Mexico D.F., Mexico: Instituto Nacional de
Investigaciones Forestales, Ciencia Forestal. 3(15):36-43.
Suggests that tropical areas planted to fast-growing tropical
species may be the best way to meet the needs for pulp
and paper. Calls for appropriate means to manage such
forests and encourages development and use of oxidation
pulping to handle these potential species rather than the
sulphate or sulphite methods used for temperate softwoods.
Rodriguez-Romero, F. 1975. The nature of wood as raw
material for pulp. Mexico y sus Bosques. 14(4):23-26.
Describes the wood anatomy and fiber morphology (includ-
ing data on length and diameter of fibers, both early and
late wood) for seven Mexican conifers, in relation to the
pulping characteristics of wood.
Rodriquez–S., J.R. 1965. The production of pulp for pa-
per from Venezuelan broadleaved species. Revista Forestal
Venezolana. 8( 12/13) : 19-37.
The characteristics, including fiber length and chemical
constituents, of 77 broadleaved woods from Venezuelan
Guayana are given,
Sandermann, W. 1979. The wood and paper industry of
Mexico. (Die Holz- und Papierwirtschaft Mexikos). Holz
als Roh- und Werkstoff. 37(2):41-51.
Describes the forest industries in Mexico in relation to pop-
ulation, forest area, production of timber and other wood-
based materials, timber usage, imports and exports, and
pulp and paper production. Based on the data, future po-
tentials are discussed for industry and the need for refor-
estation, and for more technically trained personnel.

and Paper Institute of Guadalajara University. An ex-
ample of bilateral cooperation in wood technology and
forestry between Mexico and the German Federal Republic
(Das Institut fur Holz, Zellstoff und Papier an der Univer-
sitat Guadalajara. Ein Beispiel bilateraler Zusammenar-
beit fur Holztechnologie und Forstwirtschaft zwischen den
Vereinigten Staaten von Mexico und der Bundesrepublik

Describes the function of teaching and research at the Insti-
tute, established in 1971. The principal research conducted
is in chemical wood technology; evaluation of new timber
species for pulping; forest exploitation; reforestation; and
land-use problems. The active cooperation with the Federal
Institute for Forestry and Timber at Hamburg-Reinbek,
Germany is noted.

Describes the waste or misuse of the forest resource in
Brazil in relation to the development of agriculture, forestry
and pasture; metallurgical uses of charcoal; and flooding
from hydroelectric projects. Also discusses plantations; dif-
ficulties of marketing new products; forest fires; and wood
processing technology from sawmills to pulp mills.
