2 ppm/year and has led several risks to human life including glacier melting, floods, heat waves, droughts, cyclones, hurricanes, and food security issues. Countries like China, United States, India, Russia, Japan, Korea, Germany, Iran, Canada, United Kingdom, and others contribute the lion’s share in global CO2 emissions. Burning of fossil fuels adds around 6.5 billion tons of CO2 in the atmosphere every year. In addition, ever growing population has exacerbated the deforestation activities, hence enhancing the CO2 emissions. The population increased from around 1.65 billion in 1900 to nearly 7.4 billion in 2015. Overpopulation accelerate natural resources exploitation resulting in the utilization of fossil fuels at an alarming rate. Natural processes like forest fires and volcanic eruptions are also contributing to global CO2 emissions. Consequently, the climatic shift induced extreme weather
events have posed massive damages to planet earth and gravely affected the human life and biodiversity. Since 1960 the extent of weather-related natural disasters increased three times. These disasters have caused more than 60,000 deaths worldwide mainly affecting developing countries. This chapter aims to pen down the major sources of CO2 emissions and their environmental issues.
biogas is carried out by a complex microbial process in which an appropriate environment is necessary for the multiplication of microbes and their proper functioning. Biogas generated at low temperatures using psychrophilic enzymes has a low methane content; however, other factors such as pH, oxygen content, and salt concentration also affect microbial activities and hence the quality of the biogas. The electrical energy produced by biogas from agricultural waste feedstock
is carbon zero. In Asia, biogas production is the need of the time and will
not only contribute towards a low carbon economy but also will address the longstanding issue of deforestation and environmental pollution. If increasing energy demands of a growing population in Asia and Africa are addressed through this renewable approach, then it will enhance the energy security and environment integrity of these two continents.
of systems (digesters) along with their advantages and disadvantages. This study has also involved the various factors influencing the rate of biogas production. The focus of the study was to explain the various microbial and technological advancements to overcome the constraints and drawbacks of the process, to maximize the efficiency of the
system and, also to provide a roadmap for moving toward a promising future for energy demands.
and drying to enhance the pregerminative metabolic process for rapid germination, seedling growth, and final yield under normal as well as stressed conditions. The primed seeds show faster and uniform seed germination due to different enzyme activation, metabolic activities, biochemical process of cell repair, protein synthesis, and improvement of the antioxidant defense system as compared to unprimed
seeds. There are many techniques of seed priming which are broadly divided into conventional methods (hydro-priming, osmo-priming, nutrient priming, chemical priming, bio-priming, and priming with plant growth regulators) and advanced methods (nano-priming and priming with physical agents). However, priming is strongly affected by various factors such as temperature, aeration, light, priming duration, and seed characteristics. This chapter highlights the priming mechanism
and the available technologies as a tool for superficial seed germination and crop stand. An experiment with reference to the importance of priming toward vigor seed germination and seedling growth was conducted, and its results have been added in this chapter.
produced from renewable resources including organic waste through biological processes. In the Kingdom of Saudi Arabia (KSA), the annual generation rate of municipal solid waste (MSW) is around 15 million tons
that average around 1.4 kg per capita per day. Similalry, a significant
amount of industrial and agricultural waste is generated every year in
KSA. Most of these wastes are disposed in landfills or dumpsites after
partial segregation and recycling and without material or energy recovery. This causes environmental pollution and release of greenhouse gas (GHG) emissions along with public health problems. Therefore, the scope of producing renewable H 2 energy from domestic and industrial waste sources is promising in KSA, as no waste-to-energy (WTE) facility exists. This chapter reviews the biological and chemical ways of H2 production from waste sources and availability of waste resources in KSA.
associated with significant environmental impacts subjected to various legislative
constraints. Nevertheless, the need for diversification in agricultural production and
the sustainability in energy within the European Union have advanced the role of
grassland as a renewable source of energy in grass biomethane production with
various environmental and socio-economic benefits. Here it is underlined that the
essential question whether the gaseous biofuel meets the EU sustainability criteria
of 60% greenhouse gas emission savings by 2020 can be met since savings up to
89.4% under various scenarios can be achieved. Grass biomethane production is
very promising compared to other liquid biofuels either when these are produced
by indigenous or imported feedstocks. Grass biomethane, given the mature and well
known technology in agronomy and anaerobic digestion sectors and the need for
rural development and sustainable energy production, is an attractive solution that
fulfils many legislative, agronomic and environmental requirements.
The incorporation of environmental considerations into the decision making process varies from developed countries to developing countries because of diverse set of cultural, economic, social and political patterns. At the beginning the practice of EIA was primarily confined to developed countries but it became increasingly familiar to people in the developing regions due to the active role of national and international organizations and media. Sweden adopted EIA in 1985 and initiated it on a regular basis in 1988 after the Environmental Government Bill, while in Pakistan the EIA studies for any development project became obligatory after the enactment of the Environmental Protection Act in 1997. The EIA system of developing countries is not efficient in terms of application and review. Also the appraisal of issues, decision making process and evaluation through post-monitoring is not well performed.
The stages of the project cycle are not fully integrated in processes of environmental assessment and decision making. The findings of the conducted EIA studies are also not thoroughly considered. The key reason of this shortcoming is the wrong perception of EIA because at the start intensive attention is given to the EIA content that eventually begins to lose at the time of implementation. This results in unexpected and unrequired consequences under different sets of
conditions. The aim of this research is;
1) To review the status of the EIA system in developing and developed countries by going through the developmental and evolutionary history of the EIA system in the world,
2) To provide a gap analysis of the procedural differences at the time of implementation and the consequences of differences after accomplishment of one hydroelectric power plant in each of the countries of Sweden, Pakistan and Norway,
3) To find out the reasons of failures of the EIA system in the developing countries with possible solutions and choices to remove its inadequacies in developing countries in general and Pakistan in particular.
The results indicated that the CSTR system produced 451 L CH4 kg-1 VS added at a retention time of 50 days while effecting a 90% destruction in volatile dry solids. The SLBR-UASB produced 341 L CH4 kg-1 VS added effecting a 75% reduction in volatile solids at a retention time of 30 days. The BMP assays generated results in the range 350 to 493 L CH4 kg-1 VS added.
This thesis concludes that a disparity exists in the BMP tests used in the industry. It is suggested that the larger BMP (2L with a 1.5 L working volume) gives a good upper limit on methane production. The micro BMP (100 ml) gave a relatively low result. The CSTR when designed specifically for grass silage is shown to be extremely effective in methane production. The SLBR-UASB has significant potential to allow for lower retention times with good levels of methane production. This technology has more potential for research and improvement especially in enzymatic hydrolysis and for use of digestate in added value products.
1.4 kg per day. Depending on the population density and urban activities of that area, the major ingredients of Saudi Arabian MSW are food
waste (40-51 %), paper (12-28 %), cardboard (7 %), plastics (5-17 %), glass (3-5 %), wood (2-8%), textile (2-6 %), metals (2-8 %) etc.
thousand tons of municipal solid waste (MSW) every day. While, these quantities
become 3.1 and 4.6 thousand tons per day during the Ramadan and Hajj respectively.
All of the collected MSW is disposed to landfill sites untreated, which results in
greenhouse gas (GHG) emissions as well as water and soil contamination. The
government considers reuse and recycling as optimum techniques for waste
management following source reduction. However, the current waste recycling has
been carried out mostly by informal sectors and only few recyclable materials such as
paper, cardboard, metals and plastics are recycled (10-15% of total waste). The waste
pickers or waste scavengers take the recyclables from the waste bins, containers and
dumpsites. There is an immediate need to develop public-private partnership (PPP) to
improve MSW management system in Makkah city including waste reuse and
recycling. It is theoretically estimated that only by recycling glass, metals, aluminium
and cardboard, climate will be saved from 5.6 thousand tons emission of methane
(CH4); a major source of GHG emissions and 140.1 thousand Mt.CO2 eq. of global
warming potential (GWP) with carbon credit revenue of worth 67.6 million SAR.
Similarly by recycling above-mentioned recyclables, a net revenue of 113 million SAR
will be added to the national economy every year only from Makkah city. Moreover,
technically, the waste recycling does not require high-skill labour, complex technology
and thus can be easily carried out in any urban areas like Makkah city.

Bioresource mapping: This includes the creation of a Geographical Information System to highlight sources of the organic fraction of municipal solid waste (OFMSW), slurry, slaughter waste and areas of high-yielding silage production. The system would include distribution systems (natural gas grid, electricity grid) and demand nodes (e.g. transport fleets, district heating, new towns) to propose areas with significant potential for biomethane production.
Assessment of biomethane facilities: This includes full life-cycle analysis of different biomethane facilities, including co-digestion of slurries and grass silage, mono-digestion of OFMSW, and mono-digestion of slaughter wastes. The research should allow assessment of the cost of the produced biomethane.
Digester design: This basic research should assess optimal digester systems for different feedstocks.
Agricultural impact of AD: This research includes monitoring carbon sequestration in grasslands where silage is cut and digestate is applied. This should be compared with carbon sequestration on grazed pastures. The fertiliser value of different digestates needs to be assessed along with the emissions associated with application of digestate. The research should also assess the effect on biodiversity.
