The process of cleaning one item invariably involves making something else dirty. Whether that something else is an organic or halogenated solvent, soapy water, or a rag, we seldom address the dirtying that accompanies any cleaning process. If we are to achieve environmentally benign cleaning, we must look at the life cycle of solvents employed for cleaning, including the potential for recycling, reuse, or release into the environment. Truly “green” cleaning processes not only minimize the amount of waste generated; but also they prevent the dispersal of that waste into large amounts of solvent, water, soil, or air. Dense-phase carbon dioxide is a great cleaning solvent from a pollution-prevention viewpoint. By-product CO2 generated by other industrial processes can be captured, so it is not necessary to generate CO2 specifically for cleaning. Spills of CO2 will not contaminate groundwater or create a need for soil remediation. Carbon dioxide even has advantages for the work environment, since no chronic, harmful effects are known from repeated inhalation of low concentrations of CO2. The barriers to using CO2 as a cleaning solvent have centered around two issues: the expense of high-pressure equipment and the poor solubility of many contaminants in CO2. Micell Technologies, Inc., based in Raleigh, NC, has addressed the equipment issue by using liquid CO2 just below ambient temperature (∼18–22 °C) and vapor pressure (∼50 bar). The equipment needed to contain this pressure is considerably less expensive than that needed for supercritical CO2 processes. As for the second barrier, Micell has surfactant packages that enhance the ability of CO2 to dissolve many contaminants commonly found on clothes or on metal parts. Micell is in the process of designing and bringing to market integrated CO2 solutions, including equipment and appropriate chemistries, to replace the organic solvents or water traditionally used in garment dry cleaning, metal degreasing, and textile processing. Dry cleaning is a bit of a misnomer, in that clothes are cleaned in a liquid solvent. “Dry” simply means that exposure of a garment, such as a wool suit or silk blouse, to water is minimized to prevent damage to hydrophilic fibers.

This paper discusses the importance of green cleaning for green buildings during the operations and maintenance stage. The investment on green buildings is often driven by the aim to reduce energy consumption. However, many tend to overlook the importance of the operations and maintenance aspect of the building, particularly the green cleaning aspect. Green cleaning is a major contributor to Indoor Environmental Quality (IEQ) where IEQ is one of the important criteria that should be considered during the assessment of green building performance. In Malaysia, there is no specific regulation set for green cleaning. Green Building Index (GBI) tools itself does not specifically highlighting green cleaning in their assessment tool. Thus, based on literature review, this paper discusses the benefits of implementing green cleaning and how green cleaning can contribute to achieving better green building performance.

The SME sector that has an important role in the Indonesian industry is the small and home industry (IKRT) or micro and small businesses (MSME). In everyday life, washing clothes and washing the house is an activity that is usually done by everyone, especially by the home industry. IKRT (UMK) Suradita RW 09 Suradita Indah Complex, is IKRT (UMK) in the Suradita sub-district, which produces green cleaning products guided by Universitas Mercu Buana lecturers who have been operating for one year. IKRT (UMK) was established to increase the knowledge of housewives who live in RW 09, where production is marketed in the surrounding area as well. In addition there is no good management governance, also a good marketing strategy. Based on the above, the objectives of community service are (1) using appropriate technology in the green cleaner production process, (2) improving the quality of green cleaner product formulations, (3) implementing good governance management and marketing strategies to be more effective and efficient and has sustainable competitiveness. The results of this community service are (1) appropriate technology that can be used in the production process. (2) Improving the quality of green cleaner product formulations and (3) governance management and marketing strategies. And can avoid Suradita IKRT which is more effective and efficient and has sustainable competitiveness.

Abstract The cleaning or removal of manganese stains on Cultural Heritage has not been much tested or successful so far. The aim of this article was to assess a new green cleaning gel for Mn-rich black-blue stains on different substrates. The black-blue stains were characterized at optical and chemical level through RGB data, colorimetry, optical microscope, FTIR, XRF and XPS. Mn-stained granite found on historical churches at Vila Real (North of Portugal) and glass jars of Leclanché cells, belonging to the ISEP’s Museum (Portugal) collection, were the ideal case studies to test the efficiency of Chitosan:Thiourea Dioxide (TD) cleaning gel. TD proved to be the best candidate to reduce insoluble manganese oxides, over Hydroxylamine Hydrochloride and Hydroxymethanesulfinic Acid. Cleaning assays performed on stained granite samples collected at a historical quarry and in situ application on stained granite churches showed the complete removal of the stains. Similar results were obtained on stained glass jars. This article presents an innovative, feasible and green Chitosan gel embedded with TD and phosphoric acid, applied to the cleaning of Mn-stained granite and glass substrates.
