A Strategy for Reducing Methane Emissions

Methane is an important greenhouse gas whose concentration in the atmosphere has more than doubled since pre-industrial times. It is a more potent greenhouse gas than carbon dioxide, but due to its shorter atmospheric lifetime (of 12 years) it is estimated that global emissions would only need to be reduced by about 8% from current levels to stabilize methane concentrations at today’s levels. This is a much smaller percentage reduction than those required to stabilize atmospheric concentrations of the other major greenhouse gases, CO2 and N20.

The main source of methane emissions within the EU is the agricultural sector, where emissions arise mainly from enteric fermentation in ruminant livestock, but also from livestock manure. The other major source is landfills, while coal mining and gas production and distribution are smaller, but still significant contributions. There are a range of possible measures for the reduction of emissions from each of these sectors, varying from technological options such as the collection and combustion of landfill gas, or the recovery and use of methane from animal waste, through to more general measures, often of a longer term nature, such as a reduction in the amount of organic waste going to landfill, or a reduction in livestock numbers. For some sources there are still significant uncertainties in emission factors, which make the development and assessment of abatement options difficult. In addition, there is a lack of data on the cost-effectiveness of many actions and measures. Any strategy for reducing emissions is 246 thus likely to need to combine measures to encourage the deployment of proven techniques, and to encourage research into the cost-effectiveness of options, and to improve knowledge of emissions factors and processes for some sources. This paper discusses the main options for the reduction of methane emissions and briefly summarizes the strategy paper recently prepared on this subject by the European Commission.

Introduction Palm oil frond (POF) is one of by products from palm oil plantation that indicates the disturbance of the environment in Indonesia and Malaysia as development of palm oil industry in this area now a day. Indonesia Statistical Biro (2006) reported that the production of POF was around 10,869,365 ton from around 3,682,900 ha of palm oil plantation in Indonesia. Alimon and Hair Bejo (1995) reported that the chemical content of POF is 47, 385, 787 556 g kg-1 and 5.65 MJ kg-1 for crude protein (CP), crude fibre (CF), neutral detergent fibre (NDF), acid detergent fibre (ADF) and energy metabolism respectively. On the other hand, this product might be used as an alternative ruminant feed. There was not any information dealing with POF especially its palatability. Therefore it is needed to study the utilization of this by-product in ration of ruminant. The aims of this study were to evaluate the chemical content and the palatability of POF, and proportion of POF eaten by animal.
