The high nitrogen content of animal waste provides opportunities for processing to marketable byproducts and challenges for proper management to avoid harmful impacts. Technologies are being developed to conserve and utilize nitrogen as well as other valuable constituents in animal waste. Advanced treatment technologies are also being developed for housing/waste management systems that address public concerns and protect soil, water and air quality. Smithfield Foods, Premium Standard Farms and Frontline Farmers have entered into an agreement with North Carolina to develop environmentally superior technologies that meet these goals. The 18 candidate technologies are identified and three with the longest operating period, and thus most data to date are discussed. Methods for distributing this information for implementation of cost-effective technologies through the Curriculum Project and the National Center for Manure and Animal Waste Management will be presented. This work supports priority goals to conserve and utilize valuable animal waste constituents while also protecting against negative impacts.

Laboratory and pilot scale tests were conducted to compare the effectiveness of enhanced coagulation with the more advanced technologies of ozone and granular activated carbon in treating a range of clean, eutrophic and industrially polluted waters. Particular attention was paid to the removal of disinfectant by-product precursors, organics and micropollutants that could be achieved using the various types of treatment. Reductions of up to 50% trihalomethane formation potential and between 40 and 70% organic carbon and colour were obtained using enhanced coagulation, which compared favourably with the advanced treatment processes. The more sophisticated processes were especially effective in the removal of micropollutants, this generally being in excess of 70%, which was not achievable using enhanced coagulation. pH depression using acid addition allowed for increases in organics removal at lower coagulant doses and inorganic coagulants were found to be more effective than the polymeric coagulants for organic matter removal. It was shown that the advanced treatment processes became more cost effective for larger plants and as water quality deteriorates, but for smaller water works, enhanced coagulation is cheaper.

In this paper we discussed the new design, fabrication and testing of a mechanical can crusher taking into deliberation the force analysis and ergonomic factors that will enable people to use this mechanical can crusher especially in Botswana rural areas. The process of crushing cans is of vital importance as it saves a percentage of space for can disposal and also makes it easier for these cans to be transported to recycling centers or landfill areas. The methods and processes used to bring this project to life include welding, cutting, bending, drilling and assembly operations. This project study is mainly about generating a new concept of a mechanical can crusher that is compact to transport from one location to another and makes can crushing easy and fascinating to the general public so as to promote people buy into crushing in Sub-Sahara market. Even though there are numerous sorts of the mechanical would crusher be able to as of now in presence, this model provides a more practical usage than previous one with the desired mechanical advantage of 10, machinability to crush the entire cans to 25% of their original size and 100% efficiency for the entire rounds.

Funding Cuts

As public health funding is increasingly threatened, a better understanding is needed about how periods of funding uncertainty impact program staff, activities, and outcomes. In North Carolina, 2 years of uncertainty and threats of funding cuts for a statewide youth tobacco prevention initiative contributed to reduced grantee morale and confidence about achieving program goals, displaced focus from core program activities, and caused premature loss of personnel, resulting in substantially reduced program activities and outcomes. The range of negative impacts of funding uncertainty and threats highlights the need for programs to create an infrastructure to support ongoing sustainability planning and activities.

Various municipal solid waste management (MSWM) innovations have emerged in developing countries in face of the challenges posed by increasing waste generation and poor MSWM practice. We present a methodology to assess the potential sustainability impact of MSWM innovations in a holistic manner. The Life Cycle Sustainability Analysis (LCSA) framework and the United Nations (UN) sustainable development goals (SDGs) facilitated the methodology development. The result of applying the methodology to the case of waste bank (WB) in Bandung City shows that WB potentially generates the greatest sustainability impact in the resource recovery phase and the smallest impact in the collection and final disposal phase. All negative impacts could arise in the economic dimension. Surprisingly, WB as a national strategy to achieve 3Rs would not effectively solve Bandung City’s landfill problem. Almost all SDGs would benefit from the WB program under the assumed conditions. This methodology will facilitate the decision-making in MSWM by (1) comparing available innovations to find the optimal solution, (2) identifying the hot spots and taking measures to combat the negative impacts, (3) providing the basis for monitoring the implementation process and the ex-post performance assessment.

Negative Impacts

Universities are complex organizations, so when implementing an EMS and adopting strategies, methodologies and programs they must involve the entire university system to minimize the negative impacts on the environment and, thus, lead the search for sustainable or carbon neutral organizations. Carbon Footprint was used as an indicator to measure the sustainability effectiveness of the environmental programs implemented and promoted by the EMS-ITM and how they mitigate the emission of GHGs. The calculation of this indicator was developed following ISO 14040-14044 and ISO 14064, for the ITM-Robledo campus and for the period 2015-2017. The results show the relevance and the reduction in the GHG emission levels achieved by the environmental programs studied, especially by the comprehensive solid waste management program, with which the highest levels of mitigation are achieved.
