Social Costs And Benefits

The paper quantifies social costs and social benefits of packaging waste management system in Italy from 2015 to 2030. Future social costs and benefits are estimated based on the growth of waste generated and on the stringency of recycling and landfilling targets. Packaging waste generation is projected based on macroeconomic factors, consumer practices and technological eco-innovations. Social benefits are derived by the reduction of externalities' correspondent to the achievement of packaging waste management targets. We quantify two environmental ben-efits: avoided emissions and raw materials saved. We find that social costs may rise substan-tially in the future, as total system's operations costs in 2030 may increase by 48% with re-spect to 2015, due to the growth in the quantities of packaging waste generated. Meeting recy-cling and landfilling targets set by the new Circular Economy Package would imply a further 5% increase in total social costs in 2015. This latter increase is more than compensated by so-cial benefits related to the reduction in externalities due to more stringent targets.

Bone reconstruction is a complex process which involves an osteoconductive matrix, osteoinductive signaling, osteogenic cells, vascularization and mechanical stability. Lately, to improve the healing of the bone defects and to accelerate the bone fusion and bone augmentation, bioceramic composite materials have been used as bone substitutes in the field of orthopedics and dentistry, as well as in cosmetic surgery. Of all types of bioceramics, the most used is hydroxyapatite, because of its similar properties to those of the human bone and better mechanical properties compared to b-tricalcium phosphate [1]. Currently, the most used raw materials sources for obtaining the hydroxyapatite are: bovine bone, seashells, corals, oyster shell, eggshells and human teeth. There are two common ways to obtain hydroxyapatite: synthetically and naturally. Generally, for the improvement of the mechanical properties and the structural one, hydroxyapatite is subjected to the sintering process. Considering the disadvantages of hydroxyapatite such as poor biodegradation rate, b-TCP has been developed, which has some disadvantages too, such as brittleness. For this reason, the aim of this study is to look into the effect of adding magnesium oxide on the sintering behavior, the structure and the mechanical properties of the hydroxyapatite-tricalcium phosphate composites.

Pollution  represents  a  problem  common  to economy and  public  health. Indeed, the public health, because of the  divers’  type of pollutions, is facing divers challenges for which urgent solutions are required.The biology provides approaches not only to deal with the pollution, but also to  obtain  economic  benefits. Some living  organisms  have  particular metabolisms  that allow  them  to  assimilate  and  metabolite  the polluting agents  and thus reduce the  impact  they have on both environment  and public health.  On  the other  hand,  the  metabolic  properties  of  specific organisms make  the  polluting  elements raw materials to  synthesize  other elements that are benefits  for  economy  and  non-toxic  for  the  ecology and  the  biohealth. Yet, other options such as the regulations and laws are  required  to improve the efficiency of these approaches.

Crop Waste

Significant waste but edible biomass and fuel that can be utilized as raw materials are available locally. With internal efficiencies of recycling of nutrients in an integrated farming system and appropriate technologies, such waste can be optimized for the production of livestock feed and potting soil. These items are pivotal to the productivity and efficiency of sustainable farming. Once the initial set up cost can be laid out, the operation can be self-propelled to larger scales with economic benefits at the farm level as well as at the national level. There has been the argument that livestock feed requires large acreages under grain production which is not feasible in small economies of scale and in the context of small island developing states. The paradox is that there is high cost to produce waste which is not utilized and is a loss to the enterprise.

Potential Environmental Impact

Agave distillates, such as tequila and mezcal, are alcoholic spirits representative of Mexican culture. In recent years, the demand for mezcal has increased, and with it the requirement for raw materials, bringing with it a series of difficulties. The objective of this study was to evaluate the potential environmental impact and energy demand of the production of young craft mezcal from an endemic agave (Agave cupreata) found in the central and southern Pacific area of Mexico. The potential environmental impact of the mezcal studied was obtained through the life cycle analysis methodology using a midpoint approach by the ReCiPe method to calculate the potential environmental impact with SimaPro software (version 8.2.3.0., PRé Sustainability, Amersfoort, The Netherlands). The functional unit is a young craft mezcal bottle of 750 mL with 46% Vol. Alc. The stage of highest contribution to the environmental impact of mezcal was the manufacturing/processing, contributing 59.6% of them. The energy demand of the craft mezcal resulted in 163.8 MJ/bottle of 7.5 dl. The kg CO2eq in mezcal (1.7) is higher than beer (0.63) or white wine (1.01), but lower than whisky (2.25) or pisco (3.62). These findings could allow the search for alternatives for the development of sustainable production.

At present, the excess capacity in China’s coke industry can be deployed to utilize some low-rank coal, replacing coking coal with potential economic gains, energy efficiency, and environmental benefits. This study presents a life cycle analysis to model these potential benefits by comparing a metallurgical coke technical pathway with technical pathways of gasification coke integrated with different chemical productions. The results show that producing gasification coke is a feasible technical pathway for the transformation and development of the coke industry. However, its economic feasibility depends on the price of cokes and coals. The gasification coke production has higher energy consumption and CO2 emissions because of its lower coke yield. Generally speaking, using gasification coke to produce F-T oils has higher economic benefits than producing methanol, but has lower energy efficiency and higher carbon emissions.
