Wood Utilization

Forest landscape restoration is a widely accepted approach to sustainable forest management. In addition to revitalizing degraded sites, forest landscape restoration can increase the supply of sustainable timber and thereby reduce logging in natural forests. The current study presents a spatial land use optimization model and utilizes a linear programming algorithm that integrates timber production and timber processing chains to meet timber demand trade-offs and timber supply. The objective is to maximize yield and profit from forest plantations under volatile timber demands. The model was parameterized for a case study in Thai Nguyen Province, Vietnam, where most forest plantations grow Acacia mangium (A. mangium). Data were obtained from field surveys on tree growth, as well as from questionnaires to collect social-economic information and determine the timber demand of local wood processing mills. The integration of land use and wood utilization approaches reduces the amount of land needed to maintain a sustainable timber supply and simultaneously leads to higher yields and profits from forest plantations. This forest management solution combines economic and timber yield aspects and promotes measures focused on economic sustainability and land resource efficiency.

Wood Utilization

High-yield pulps (HYPs), such as CTMP (chemi-thermo-mechanical pulp), are attractive due to their low cost and high wood utilization. However, their drawback of rapid brightness reversion (yellowing) limits wide use of the HYPs. In this study, a fungus, Fusarium concolor X4, was applied to treat poplar CTMP for exploring the effects of biotreatment on brightness and light-induced yellowing of the pulp. The results indicated that the biotreatment with Fusarium concolor X4 could improve the brightness of poplar CTMP and inhibit light-induced yellowing of the pulp. The yellowing inhibition mechanism was explored by the analysis of enzyme production regularity during biotreatment, changes in chemical components, and the UV-Vis absorption spectra and FTIR-ATR spectra of pulps before and after biotreatment.

Change Mitigation

The forestry and forest-based sector play a significant role in climate change mitigation strategies and can contribute to the achievement of a climate-neutral economy. In this context, the ability of harvested wood products (HWP) to sequester carbon is of significant importance. The objective of this work is to make a projection of climate change mitigation potential of HWP, under different scenarios of wood utilization in Slovakia. This study builds on the comparison of different scenarios of industrial wood utilization till 2035 and presents the resulting impacts on the national carbon balance. The results suggest that the development of timber supplies after 2020 in Slovakia will be influenced, in particular, by the future changes in the age distribution and tree species composition as well as the extent of future accidental felling. Consequently, a predicted structure and availability of wood resources in Slovakia will be reflected in a higher share of the production of products with shorter life cycle and thus will negatively affect the carbon pool in HWP. By comparing the results of the four designed scenarios, it follows that the scenario with the greatest mitigation potential, is the one assuming the optimal use of wood assortments and limitation of industrial roundwood foreign trade.

In the last 10 years, I would venture to say, we foresters in the woods industries and governmental forestry services, have seen more developments in forest harvesting methods, wood handling, transportation methods, woods workers' living conditions, and in wood utilization than have been witnessed in the previous 100 years of logging history. Reflect for a moment on some of the more obvious changes of the last 10 years—woods workers and their families living comfortably on the job; power saws superseding bucksaws; tractors and trucks replacing horses; and former nuisance or weed species of trees becoming more useful and therefore more valuable. These are but a few of the changes which we have seen in the last few years.The developments of which I speak are not local ones by any means. This march of progress exists from one end of Canada to the other and I believe that this greatly accelerated progress is causing a degree of confusion in the minds of many foresters who are responsible for the proper management of our forests so as to ensure a continued supply of forest products for future generations of Canadians.The existence of this confusion is illustrated by the fact that while in one part of Canada it is apparently necessary to have Government legislation to ensure sawmills a supply of sawlogs from pulp and paper company cutting operations, in another part of Canada private enterprise has seen fit to invest millions of dollars in a paper mill to be run almost entirely on waste from sawmill operations. Without a doubt foresters played their part in formulating and guiding both of these plans of action.Many surveys and calculations were undoubtedly carried out by Company foresters before a pulpmill was established on the basis of using sawmill and sawlog operation waste. Similarly much time and energy were probably spent by highly placed Government foresters before advising their Parliament of the necessity of enacting legislation to ensure the production of sawlogs on pulp cutting operations thus apparently condoning "wasteful practices" or at least poorer utilization than if the togs were produced as pulpwood.

ABSTRAKPotensi limbah akibat pemanenan kayu sampai saat ini masih cenderung tinggi yang dapat menyebabkan rendahnya efisiensi pemanfaatan kayu. Hal ini sebagai kecenderungan pemborosan bahan baku kayu, sedangkan saat ini terjadi ketimpangan antara ketersediaan bahan baku yang terus menurun dengan kebutuhan kayu untuk industri. Tujuan penelitian adalah untuk mengetahui potensi limbah pemanenan kayu pada dua pengusahaan hutan di Kalimantan dan pengaruhnya terhadap efisiensi pemanfaatan kayu. Metodologi penelitian dengan mengukur potensi tegakan, volume kayu yang dimanfaatkan, volume limbah kayu setelah pemanenan kayu, menghitung indeks tebang, indeks sarad dan efisiensi pemanfaatan kayu. Hasil penelitian menunjukkan bahwa: (1). Rata-rata volume kayu yang dimanfaatkan pada IUPHHK-HA PT Karya Lestari (PT A) dan PT Inhutani II (PT B) masing-masing adalah 16,759 m3/pohon dan 6,742 m3/pohon; (2). Rata-rata volume limbah kayu pada PT A dan PT BI masing-masing adalah 2,410 m3/pohon dan 0,472 m3/pohon; (3). Proporsi limbah tunggak, pangkal batang, ujung batang pada PT A dan PT B masing-masing adalah 0%, 81,54%, 18,46% dan 70,25%, 21,78%, 7,97%; (4). Rata-rata efisiensi pemanfaatan kayu pada PT A dan PT B masing-masing adalah 88% dan 86%; dan (5). Pengaruh potensi limbah pemanenan kayu terhadap efisiensi pemanfaatan kayu ditunjukkan dengan model persamaan Y = 0,971 - 0,0341X. ABSTRACTPotential logging residue from forest harvesting operation is significantly high at tree quantities of logging. This reflects in a low efficient of harvesting that may derive wasteful in using forest resources. In the contrary, the wood supply is not equal to wood demand.  The wood supply continously decrease so that it is not able to support the demand of wood industry.  The aim of research is to find out the potential logging residue on forest harvesting operation and its effect on wood utilization at two companies in Kalimantan. Research method used by measuring potential forest standingstock, potensial use of wood volume and logging residue from the harvesting operation. The study also measures felling index, skidding index and efficiency of wood utilization. Research result showed that: (1). Average of wood volume used in IUPHHK- HA PT Karya Lestari (PT A) and Inhutani II (PT B) are consecutively 16.759 m3/tree and 6.742 m3/tree; (2). Average of logging residue PT A and PT B are 2.410 m3/tree and 0.472 m3/tree; (3) The percentage of the logging residue at tha bottom stem, middle stem, and upper stem at PT A are 0%, 81.54%, 18.46% and PT B is about 70.25%, 21.78%, 7.97%; (4). The average of timber utilization efficiency (TUE) at PT A and PT B are 88% and 86%; and (5). The equation derived from the comparation model between the effect of logging residue from forest harvesting operation and efficiency of wood utilization is Y = 0.971 - 0.0341 X.Keywords: forest harvesting, potential of logging residue, efficiency, native forest Sitasi: Suhartana, S dan Yuniawati (2018).
