#Scichallenge2017 With this presentation we are able to demonstrate how, thanks to the in vitro way of plant cultivation, a crop can be used to obtain renewable energy, and, therefore, it can also solve big environmental problems.
Geothermal energy can be harnessed by running pipes deep underground to take advantage of the earth's consistent temperature. This allows for efficient heating and cooling of homes without heavy reliance on weather-dependent solar panels. Researchers are also working on improving solar cell technology using quantum dots and multi-exciton generation to capture more solar energy. Additionally, some universities are developing methods to produce renewable hydrocarbon fuels using bacteria, sunlight, and carbon dioxide to potentially reduce greenhouse gas emissions and dependence on fossil fuels. Small everyday practices like short showers, collecting rainwater, and reusing water can also help conserve resources.
Biomass is Through photosynthesis plants convert sunlight energy into chemical energy.
Biomass is stored sunlight energy that can be converted to:

Biomass and waste-to-energy have potential benefits but have not been fully utilized in Pakistan. Developing these sources could generate clean energy, reduce environmental impacts from waste disposal, and create jobs. Biogas in particular is a significant biomass energy that makes good use of animal waste for fuel and fertilizer. The Alternative Energy Development Board is working to promote biomass and waste-to-energy projects in Pakistan, having issued letters of intent for several planned plants that would convert various waste materials into electricity.
The document discusses various non-conventional energy sources including solar energy, wind energy, tidal energy, geothermal energy, biofuel energy, and biogas energy. These sources are considered renewable as they can be replenished naturally and do not rely on finite fossil fuels. Specific technologies are described for each source such as photovoltaic cells for solar energy, wind turbines for wind energy, and tidal barrages for tidal energy. Both advantages like being renewable and low cost, and disadvantages like high initial costs and location dependence are noted.
P2P’s microalgae technologies (Photobioreactor design, nutrient formulation and possibly water recycling) will make production of microalgae biofuels coupled with carbon capture more sustainable in terms of productivity and cost.

Biomass refers to natural materials that contain stored solar energy, such as wood, straw, manure, garbage, and alcohol fuels. It is found in places with abundant crops, trees, animals, and garbage. Biomass can be used on both large and small scales. The most common way to use biomass for energy is to burn it to produce heat, which is then used to boil water and power generators. While biomass technology is mature, biofuel technology is still experimental. Biomass accounts for around 15% of the world's total energy supply. It has low costs but there are concerns about deforestation and health impacts from biomass burning.
This document discusses biomass energy, identifying fuels like trees, grasses, crops and residues that can be used, and describing how biomass produces electricity by heating water into steam to turn a turbine. It lists current uses of biomass as ethanol, space heating and cooking, and notes pros as biomass being available worldwide and potentially sustainable, while cons include needing fossil fuels for harvesting and transport and high production costs.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Energy crops with multiple benefits #Scichallenge2017
1. Energy crops with multiple
benefits
By: Fabiana Coloma Calderón and Alejandra Lapido Díaz-Vieito
2. 1.- In vitro cultivation
It is a way of cultivation in which an explant will
result into various plants.
3. 2.- Characteristics of in vitro
growing
The explant is planted
in a jar with a
transparent gelatinous
base that contains
nutrients, vitamins
and rooting hormones
in an incubator under
a white LED light. This
will result in a much
faster growth.
4.
5. 3.- Environmental problems
• Greenhouse effect
• Global warming
• Deforestation
• Excessive use of
non-renewable
energy
6. 4A.- Beneficial uses of the in
vitro way of cultivation
1.- Energy crops: are plantations with specific
characteristics such as fast growth and effective
reproduction (which is easily obtained thanks to this
method). For the purpose of producing energy, like
thermal, electrical or to produce bio-fuels.
7. 4B.- Our idea
On one hand, our plantation will be used for the
production of renewable energy (biomass: pellets,
biofuels...), because it is an energy crop.
8. 5A.- Beneficial uses
of the in vitro way of
cultivation
2.- Thanks to in vitro plantation, we will be able to
reduce deforestation. This causes the
greenhouse effect, which leads to global warming
produced by the emission of gases into the
atmosphere. Deforestation reduces the
transformation of CO2 in O2.
9. 5B.- Our idea
On the oder hand, We have thought of applying organic
agriculture, using the technique of in vitro cultivation.
This will help put an end to the greenhouse effect as the
trees destroyed by human action would be quickly
replanted with this energy crop and the transformation
of the CO2 to O2 would be faster and more efficient
thanks to the big number of plants that have been grown
in order to create this crop. It will also increase
biodiversity.
10. 5C.- Our idea
Create energy crops with
multiple benefits thanks to in
vitro cultivation.
