 sawmills and sometimes in the form of chips cut to their require- 
 ments . 
 
 (b) Pulpwood, fuelwood, posts, stakes, mine props recovered 
 from logging waste are salable in many areas, 
 
 (c) Green sawdust and coarser waste occurring at plants having 
 steam boiler installations often find most profitable utilization 
 as fuel. 
 
 (d) Green hardwood sawdust for sale to packing plants for 
 smoking meat is advantageous in some localities. 
 
 (e) Green softwood sawdust and pole material are used in some 
 ore smelting plants as a mix or flux. 
 
 (f) Sawdust, shavings, and chipped wood are receiving increased 
 attention when properly handled as a soil conditioning or mulching 
 material. As stable bedding and absorbent of liquid manure for 
 subsequent soil improvement some of this material has long been used 
 advantageously. Extension of this idea to recover and produce 
 fertilizing matter from outdoor cattle feeding pens is taking place in 
 some instances. Also, composting waste wood material with nitrogen 
 additive, bacterial inoculation, and sewage effluent is being done in 
 certain instances. 
 
 (g) Dry sawdust often finds fairly ready sale for a variety of 
 specialty uses, in addition to wood flour and briquettes mentioned 
 urder "Conversion," including fur and metal cleaning, sweeping 
 compounds, packing, and stuffing and the like. 
 
 (h) Sale of dry sawdust and shavings through established dealers 
 in metropolitan centers is often advantageous , 
 
 (i) Solid waste, such as slabs, edgings, and factory cuttings, 
 is often recovered most advantageously for sawed products, such as 
 dimension cuttings, handle or turning squares, short lumber, container 
 stock, and the like. 
 
 (j) Solid wood waste, especially of hardwood cordwood, can often 
 be converted to charcoal advantageously, especially for domestic uses 
 for barbecue and picnic purposes. 
 
 More detailed discussion of the above measures and allied subjects is 
 contained in other Forest Products Laboratory reports.
