Biofuel production from waste wood - (Product Life Cycle Assessment Coursework

Biofuel production from waste wood - (Product Life Cycle Assessment (PLCA)) - Coursework Example However, wood pellets have drawbacks including requirement for large storage facilities and continuous removal and control of ashes (Chen, 2009, p 2). It is indispensable to comprehend that use of wood pellets as a substitute energy source to fossil fuels remains essential in significant reduction of global warming effects and minimal emissions of green gases. The report aims at understanding the life cycle of wood pellets and its contribution to environmental degradations. In addition, the report provides an assessment of wood pellets life cycle in relation to its human effects. Besides, the fundamental objective of the report is to assist wood pellets producers in communicating with customers. Moreover, the producers would also ensure better environmental management. Life cycle assessment (LCA) relates to an environmental evaluation device that focuses on analyzing environmental impacts associated with use of a process or product within its entire duration or life. The inherent assessment remains achievable through creation of a systematic model that can carry out quantification of energy and materials consumption and calculation of released wastes and emissions (Manyele, 2007, p 142). Such computation of effects occurs of life cycle of the process or product from raw materials extraction, production, transportation, reuse and use phases, and consequent recycling stage. Therefore, there exist four significant steps in performing LCA including last step called interpretation, life cycle impact assessment, inventory analysis, and the first step being goal and scope definition. Assessment of wood pellets life cycle is domineering in quantifying and analyzing its global warming potentials in comparison to fossil fuels. Moreover, the assessment remai ns vital in communicating with customers that constantly uses fuels and more importantly to investigate impacts of the energy on the environment.

Parole - Essay Example However, there has been a consensus among the players within the criminal justice system that incarceration is not the most appropriate measure to all offenders. It is in the light of this consensus that parole and probation systems were developed in order to provide alternative and appropriate ways of addressing specific types of offenders (Welsh and Harris, 2008). These systems have had remarkable impacts within the criminal justice system; but they have also had some shortcomings as well. Particularly, parole has been regarded as an early release option that puts the public at unnecessary risk. On the other hand, there are those who argue that it allows the re-integration of offenders into the community and provides better prospects for rehabilitation (Broadhurst, 2001). This paper will seek to understand the parole system by discussing its pros and cons. In addition, it will discuss whether parole is currently over-utilized or under-utilized in Australia, or whether proper balanc e has been struck. Yoshimura (2000) defines parole as a process that involves conditionally releasing an offender from prison so that he or she can serve the remaining sentence in the community according to the sentences terms that the court would impose. Often, offenders released under parole serve the remaining sentence in the community under community corrections officer supervision. Parole is considered as a conditional release from the prison because the release of the offenders is based on certain conditions such as prisoners agreeing to obey specific restrictions imposed by the court. It should be noted that the parole release decisions basis vary across jurisdiction and time (Proctor, 1999). For example, parole can be offered as an entitlement to offenders after they have served a specified minimum imprisonment term. Similarly, parole can be used as a reward for offender’s good behavior. Nonetheless, the bottom line is that granting of release on parole is based on
