· 11. Recognize contributions. A job well done deserves praise, and it's not just a feel-good thing to do—research by some of the world's top analysts shows that recognition is an incredibly powerful element of the working relationship. It also drives more success for the individual and for the organization.
· Settling or flotation rate, speed of processing. The rate of separation of wastewater solids in a waste treatment plant can limit the throughput of settling or flotation units. On the other hand, if methods can be developed and optimized to accelerate separation, then the size and capital costs of the plant might be reduced.

· Hydrometallurgical techniques are also widely used for the recovery and separation of precious metals from spent catalysts. The processes can be categorised into two types support dissolution and precious metal dissolution . In the first of these, the support is dissolved with a nonoxidising acid or base, after which the precious metals remain as a residue.
· High Pass filter setup for the Frequency Separation technique isn't all that bad, and shouldn't be completely written off as an inaccurate way to separate spatial frequencies.
· The EPA estimates gas capture in the first five years may be as low as zero, which means we’re already doing substantial damage to our climate.
· Download our one-page handout on Zero Waste as a pivotal climate solution. Stop Trashing the Climate report Stop Trashing the Climate , co-authored by the Institute for Local Self-Reliance, Eco-Cycle and GAIA, proves a Zero Waste approach is one of the fastest, cheapest and most effective strategies to protect the climate.
· Putting GHG emissions in context. Climate change is now the most serious global environmental threat. 1 Its potential impacts include global warming, sea level rise, increased extreme weather events, and altered rainfall patterns. Climate change is a direct consequence of elevated greenhouse gas (GHG) concentrations in the atmosphere, resulting in increased atmospheric heat
To turn our waste into something we can re-use. That is exactly what Renescience technology does. Using enzymes, mechanical sorting, recycled water and anaerobic digestion, Renescience separates waste into recyclables. Then it liquifies the organics from the waste and turns it into green energy. Waste management has seen tremendous
· In 2015, the City Council adopted new zero waste requirements that aim to make Boulder a zero waste city. This ordinance requires all residents to subscribe to waste hauling services, all businesses to separate recyclables and compostable items from the trash, and all property managers provide recycling, composting, and trash services to their tenants.
Deconstruction and source separation of materials allows for reuse of the materials (which is better than recycling) and a higher recycling rate for those materials that cannot be reused. Despite Palo Alto’s already high recycling rate for construction projects, approximately 44% of what Palo Alto sends to the landfill comes from construction and demolition projects.
· Zero Waste policies in Penang, the state has been performing fairly well in recovering materials from its s and businesses. It boasts the highest recycling rate in Malaysia at 43%, more than double than the national average of 21%.1 Penang’s waste segregation at source policy was enforced on June 1, 2017,
· It has had remarkable successes, among them the implementation of a “zero waste” policy. What is zero waste? Zero waste is the vision to build a society that enjoys a sustainable rubbish-free lifestyle, with no need for incineration or landfill. The three Rsreduce, reuse and recycleare central to discussions about waste management, as are the four Lslocal, low cost, low impact and low tech.
· The efficient, selective, and economical sorbents for the removal of Sr radionuclides are largely needed for the decontamination of effluents with high salinity. In this study, the removal of Sr

· Removal of Sr was fast (5 min for removal at 8.80 mg/L), with high maximum sorption capacity (252.5 mg/L), and independent on the initial pH in the range 3.5–9.0.
· A key prerequisite for a high-quality recycling system is the source separation of materials that have market values. In Germany and in Italy, for example, the official input-calculated recycling rate is, therefore, high, but less than 50% of the introduced material is, in fact, recycled. Zero Waste activists tend to claim that WtE is a
Adjust the sliders to reflect waste diversion strategies and goals. See Best Practice Strategies 2.08-2.14 to increase waste diversion, which can allow buildings to reach 90% capture rate for all streams. Design waste storage that can accommodate current diversion rates and a zero waste future.

· 1. Introduction. Waste management is a crucial area related to the economic status of a country and the lifestyle of its population. Solid waste management can be defined as a discipline associated with the control of generation, storage, collection, transfer and transport, processing and disposal of solid wastes (Tchobanoglous 1993) and in spite of the aggressive economic development
· Zero Waste International Alliance. Zero Waste The conservation of all resources by means of responsible production, consumption, reuse, and recovery of products, packaging, and materials without burning and with no discharges to land, water, or air that threaten the environment or human health. Note This definition was updated in December of 2018.
· Supercritical fluids may eventually offer an attractive separation process by selectively dissolving out fractions of PCB waste using different solvents at room temperatures and effective solvent recovery systems would reduce pollution to almost zero levels depending on the vapor recovery process
· “Go Green,” “Green Business,” “Green Office,” and Zero Landfill" are some of the buzzwords of the current era. While more and more businesses are going green every day, some businesses still lag. Others lose momentum when they run out of waste reduction ideas. Here are some easy-to-implement office waste reduction tips and ideas.
· These data are obtained from a process cycle consisting of four steps, namely ion removal for ∼120–140 s, a ‘concentrate’-step (where voltage is reversed and the flow rate is set to zero, with a duration of ∼50 s), a ‘waste’-step (in which the flow rate Φ is returned to the original value, with a duration of ∼30 s) and a ‘prepurify’-step (in which the voltage is returned back to the original, positive, value).
