Initiatives cover areas from cartography to government policies, public services or environmental research. As the collection and engagement with CGD rises in relevance and visibility, public institutions can learn from existing initiatives about what CGD initiatives do, how they enable different forms of sense-making and how this may further progress around the Sustainable Development Goals. This report examines different approaches to doing and organising CGD, as well as how governments already engage with these types of initiatives. It identifies three ways how citizen-generated data may relate to the SDGs, underlining the importance for public institutions to further support these initiatives. These include: 1) CGD initiatives create new kinds of relationships, participation and public spaces between public institutions, civil society groups and citizens, 2) Beyond closing data gaps, CGD initiatives also provide alternative ways of measuring and help informing, expanding, and improving existing monitoring efforts, 3) CGD initiatives can inform public policy, behavioral change and other actions towards implementing and achieving the SDGs.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"98 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132326574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researches have been shown that biomass use instead of fossil fuels for energy conversion. Biomass sample may also include herbaceous and agricultural residues like rice husks, wheat straw, wood, sunflower shells etc. Properties of biomass like heating value, moisture content, ash content, susceptibility to slagging and fouling and volatile content makes it a good fuel and appropriate modification of biomass ash with chitosan nanocomposite have been shown to effectively remove heavy metals from industrial wastewater. Guar gum nanocomposite will be used to adsorb heavy metal from the waste water stream .Due to its thickening, emulsifying, binding and gelling properties, quick solubility in cold water, wide pH stability, film forming ability it can be used as an adsorbent in the adsorption process. Guar gum is the powdered endosperm of the seeds of the Cyamopsis tetragonolobus which is a leguminous crop. The endosperm contains a complex polysaccharide called galactomannan, which is a polymer of d-galactose and d-mannose. Characterization of nanocomposite by using TGA, XRD, TEM ,SEM ,FTIR shows the better possibility as chemical adsorbents for entrapping metals ions present in waste water.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128461493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Synthesized novel graphene oxide-beta-cyclodextrin (GO-CD) composites is applied as adsorbent for adsorption and elimination of hazardous endocrine disrupting compounds, such as Methylene Blue from the solvent phase of an aqueous solution. Methylene Blue from aqueous solutions by batch adsorption technique under varying conditions such as contact time, pH and temperature. Lower solution pH (3 to 5) favoured the adsorption of reactive dye onto graphene oxide-beta-cyclodextrin composites. Endocrine disrupting compounds are highly toxic substances that cannot be removed from treated waste water through conventional methods. The optimized values of effective parameters were 20 minute (contact time), 20mg (adsorbent dosage), and 7.5(pH) and 0.00001 (initial concentration) these values were optimized using batch adsorption study. Hence, the developed adsorbent could be efficiently used for rapid adsorption and removal of noxious impurities. The results indicated that graphene oxide-beta-cyclodextrin composites have shown reduction in colour of waste water by 60-80% and also have shown reduction in other polluting parameters.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122729935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we outline how systemic innovations, such as whole-house energy ‘retrofit’, may require new business models before they gain widespread adoption. Through a series of semi-structured interviews and document analysis, we undertake a case study of the ‘Energiesprong’ retrofit business model - contrasting this with the incumbent ‘atomised’ market model. We highlight the central role of an innovation intermediary - the Energiesprong ‘market development team’, in this business model innovation, and how Dutch policymakers sought to promote business model innovation through creation of this intermediary. In doing so we develop a novel framework - combining the components of business models with the functions of intermediaries to illustrate this case. Finally, the paper suggests this case and framework could provide lessons for how intermediaries and in turn policymakers might foster business model innovation in other sectors.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121529409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rapid growth of smart-mobile phones usage in developing countries resulted in several advantages compared to other alternatives in term of costs, geographic coverage and ease of use. This research was conducted in North Kordofan Sate to explore the role of smart-mobile phone in accessing agricultural information. Primary data were obtained by structured questionnaires and focus group discussion through participatory rural appraisal and observation while secondary data were collected from scientific journals, books and authenticated web sources. A number of 230 respondents (10% from total farmers) were interviewed and five focus group discussions were done. Statistical Packages for Social Science (SPSS) version 22 was used to analyze the data with aid of descriptive statistics and Chi-squire Test. The result indicated that most of the respondents fall in age group between 21-40 years, and they depend on farm activity. There was 90% of farmers processed mobile phone since more than three years ago, 90.8%continuedto use smart mobile phone to access agricultural information and showed positive contribution towards income generation. The results also revealed that there was positive perception towards using mobile phones which showed more efficient in use than radio and TVs. The results showed great advantages of using smart mobile phone where 75.2 % of respondents preferred to get agricultural information, logistics and other needs through successful communication in the mid of agricultural season. Results of Chi-squire test showed significant differences between the parameters tested. The study recommended that farmers should be connected with mobile phones to admit ease communication with agricultural extension offices and quick access to their needs and logistics.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130741120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
