To get more insight in the environmental performance of the Suiker Unie beet sugar, Blonk Consultants performed a comparative Life Cycle Assessment (LCA) study on beet sugar, cane sugar and glucose syrup. The system boundaries of the sugar life cycle are set from cradle to regional storage at the Dutch market. For this study 8 different scenarios were evaluated. The first scenario is the actual sugar production at Suiker Unie. Scenario 2 until 7 are different cane sugar scenarios (different countries of origin, surplus electricity production and pre-harvest burning of leaves are considered). Scenario 8 concerns the glucose syrup scenario. An important factor in the environmental impact of 1kg of sugar is the sugar yield per ha. Total sugar yield per ha differs from 9t/ha sugar for sugarcane to 15t/ha sugar for sugar beet (in 2017). Main conclusion is that the production of beet sugar at Suiker Unie has in general a lower impact on climate change, fine particulate matter, land use and water consumption, compared to cane sugar production (in Brazil and India) and glucose syrup. The impact of cane sugar production on climate change and water consumption is highly dependent on the country of origin, especially when land use change is taken into account. The environmental impact of sugar production is highly dependent on the co-production of bioenergy, both for beet and cane sugar.

Seismic Resilience

<p>This paper investigates the life-cycle seismic resilience of aging road networks with reinforced concrete (RC) bridges under the effects of climate change. The physical damage suffered by the exposed bridges is related to traffic limitations implemented over the network. A probabilistic framework is proposed to aggregate the time-variant seismic capacity assessment of RC structures exposed to chloride-induced corrosion with the traffic response of the transportation network. The life-cycle seismic resilience of a simple road network is evaluated based on the restoration of the network functionality guaranteed by the post-event recovery of the damaged bridge. The results highlight the detrimental effects of the progressive increase in the deterioration rate induced by climate change, impairing the seismic capacity of single bridges and, in turn, the seismic resilience of the overall transportation system.</p>

Climate change is one of the main current problems, it concerns the entire human population since its effects are worldwide, especially now we have seen its consequences, according to Menghi (2007), the average global temperatures grew by more than 0.5 ° C in the last century, and the glaciers are disappearing from the earth. The greenhouse effect generated mainly by the gases of the same name (GHG), is the fundamental factor of climate change. Construction is one of the ways in which the human being contaminates in a constant way this due to urban growth and the demand for infrastructure that this generates. This research has the purpose of determining the KG-CO2 / M2 generated by a 44 m2 house of interest type INFONAVIT using the Life Cycle methodology (ACV) of the products or materials, established in ISO 14040, employee an inventory of KG-CO2 emissions from building materials, obtained from various bibliographic sources and databases and using the work volumes required to build the house. The results obtained of 161.57 Kg-CO2 / M2.

Recovery Methods

The effects of climate change and government legislation has changed the way in which manufacturers can dispose of their waste, encouraging SMEs to source alternative disposal methods such as those indicated in the waste hierarchy. It is economically and environmentally beneficial to use product recovery methods to divert waste from landfill. The environmental impact of two product recovery methods, remanufacturing and repairing, has been compared via a carbon footprint calculation for a UK-based SME. The calculation has identified that repairing has a lower carbon footprint than remanufacturing, however this only extends the original life-cycle of the product, whereas remanufacturing provides a new life-cycle and warranty, and therefore seen as the most preferable method of product recovery to support sustainable manufacturing.

Cumulative Energy Demand

Wind technology is considered to be among the most promising types of renewable energy sources, and due to high oil prices and growing concerns about climate change and energy security, it has been the subject of extensive considerations in recent years, including questions related to the relative sustainability of electricity production when the manufacturing, assembly, transportation and dismantling processes of these facilities are taken into account. The present article evaluates the environmental impacts, carbon emissions and water consumption, derived from the production of electric energy of the Villonaco wind farm, located in Loja-Ecuador, during its entire life cycle, using the Life Cycle Analysis method. Finally, it is concluded that wind energy has greater environmental advantages, since it has lower values of carbon and water footprints than other energy sources. Additionally, with the techniques Cumulative Energy Demand and Energy Return on Investment, sustainability in the production of electricity from wind power in Ecuador is demonstrated; and, that due to issues of vulnerability to climate change, the diversification of its energy mix is essential considering the inclusion of non-conventional renewable sources such as solar or wind, this being the only way to reduce both the carbon footprint and the water supply power.
