6. The potential use of wood residues for energy generation
Air-drying of mill waste, time and space permitting; is preferable under covered well-ventilated areas, especially for the smaller-sized residues such as sawdust, which is more liable to absorb rainfall and takes longer to air-dry than say mixed wood waste. Green whole chips and mixed waste, when stored outside in piles for several months, may ...
Sieving and milling - Glatt - Integrated Process Solutions
The term 'sieving' describes the separation of undesirable fine and coarse particles. For sieving, a vibration sieve is typically used. For homogenizing granules, we use grinders that work according to the principle of rotor sieves for homogenization. Coarse particles are reduced to the desired size. Rotor sieves for homogenization are used ...
3 Municipal Wastewater and Sludge Treatment
processes, dry weight is a more useful basis for expressing the amount of sludge from municipal wastewater treatment. Typical primary and secondary wastewater treatment produces a total of about 1.95 lbs (0.94 kg) of dry solids per 1,000 gal (3.78 m3) of wastewater treated (Metcalf and Eddy, 1991).

Waste in the food industry is characterized by a high ratio of product specific waste not only does this mean that the generation of this waste is unavoidable, but also that the amount and kind of waste product which consists primarily of the organic residue of processed raw materials, can scarcely be altered if the quality of the finished product is to remain consistent.
Dry Milling - an overview | ScienceDirect Topics
Dry milling and wet milling of cereal grains are used to produce ethanol and to partition the grains into an array of feed components (Figure 2).Wet milling is a more complex process and requires high-quality grains to produce high-value products suitable for human use. Some of the co-products, such as maize gluten meal, may be marketed in higher value markets such as the pet food …
