answer:Upon reviewing, I realize my initial response may have been confusing regarding the specific roles of a Materials Recovery Facility (MRF) and a Transfer Station. Here's the correct matching based on the intended functions of each facility: Materials Recovery Facility (MRF): - might be used to improve the quality (or decrease "contamination") of recyclable materials - receives recyclable material for further processing and subsequent sale Transfer Station: - can receive both waste and recyclables - might be used because the volumes of waste or recyclables collection is low and infrequent - might be used because the distance to the final destination is far and perhaps some additional sorting can reduce transportation costs The corrected allocation indicates that the MRF's primary functions are to decrease contamination of recyclable materials and to process these materials for sale, whereas a Transfer Station serves as a collection and forwarding point for both waste and recyclables, especially when logistical concerns such as volume and distance are at play.

answer:The advantages to source sorting of waste prior to collection include: - can improve the quality of the recoverable products (less contamination) - can increase the amount of recoverable resources in the waste, if done properly - can be cheaper to do at the source rather than at the destination

answer:1. Active/Plateau Phase - Rapid increase in microbial activity accompanied by a rapid rise in temperature, followed by temperature equilibrium until readily available nutrients start to decrease during decomposition. These higher temperatures reduce pathogens. Requires oxygen. 2. Lag Phase - Bacteria, actinomycetes, and fungi begin to proliferate, breakdown of waste begins, temperature starts to rise due to exothermic processes. Requires oxygen. 3. Maturation Phase - All easily decomposed organic matter is depleted and the number of microbes declines. Temperature begins to decrease. Oxygen not required.

answer:A Mid-Side (M-S) processor in audio refers to a technique or tool used for encoding and decoding stereo audio signals to and from Mid-Side format. This method of processing can significantly enhance stereo imaging and provide more flexibility in mixing and mastering by allowing separate control over the middle (Mid) and sides (Side) components of a stereo signal. In more detail: - **Mid (M)**: Represents the center content of a stereo image, essentially what is common or similar in both the left and right channels. It could be considered the mono part of the signal, encompassing elements like vocals, bass, or snare drum that are usually centered in a mix. - **Side (S)**: Represents the difference between the left and right channels, capturing the stereo information or the elements that vary between the two sides. This includes panned instruments, stereo effects, and ambient sounds that contribute to the sense of width and depth in a mix. How it works: 1. **Encoding**: A Mid-Side processor initially encodes a regular stereo signal (left and right channels) into Mid and Side components. This encoding is done mathematically, where the Mid signal is derived by summing the left and right channels (L+R), and the Side signal by subtracting the right channel from the left (L-R). 2. **Processing**: Once encoded into Mid and Side channels, these components can be processed separately. For example, one might increase the level of the Side components to enhance the sense of stereo width or apply equalization (EQ) differently to the Mid and Side channels to shape the tonal balance of the center versus the edges of the stereo field. 3. **Decoding**: Finally, the processed Mid and Side signals are decoded back into the conventional stereo format (left and right channels). This decoding is the reverse of the encoding process, where the left channel is recovered by adding the Mid and Side signals (M+S), and the right channel by subtracting the Side from the Mid (M-S). Applications: - Enhancing or narrowing the stereo width of a mix or track. - Independent tone shaping of the center and sides of a mix. - Fixing stereo imbalances or phase issues. - Creating more immersive stereo effects. Mid-Side processing is widely used in mastering, mixing, sound design, and broadcasting, offering engineers and producers a powerful tool for sculpting stereo images and achieving precise control over the spatial aspects of their audio projects.
